Hydrogen Sulfide (H2S)

A molecule can be polar or nonpolar, depending on how it is laid out. This is determined by how atoms are joined, along with the placement of the electron pair surrounding the central element.

Hydrogen sulfide is a corrosive compound with a weak dipole-dipole interaction. It has a lower boiling point even when in gas form at the room’s temperature.

Bond Angle

Hydrogen sulfur (H2S) is a covalent compound consisting of 2 hydrogen atoms and the sulfur atom. It’s a colorless gas that has a strong odor similar to the smell of eggs that are rotten. In this article, we’ll examine how H2S bonds and the elements that affect the angle.

Bond Angle Of H2s

The bond angle of H2S may be measured by studying the Lewis structure. The Lewis structure of H2S indicates that it has a bent form that is the result of the single pair of electrons in the sulfur atom. Hydrogen atoms bond with the sulfur atom, and the two electron pairs occupy the two remaining positions within the sulfur valence shell.

It is believed that the VSEPR theory (Valence Shell Electron Pair Repulsion Theory) suggests that the form of molecules is determined by the repulsion of electron pairs. For H2S, the two-electron bonding pairs between hydrogen and sulfur atoms and two electron pairs on the sulfur atoms are at war and form a bent shape. Repulsion results in the bond angle not exceeding 180° this is considered the optimal angle for linear geometry.

The actual bond angle of H2S is 92 degrees. This is significantly less than the optimal bond angle of 180 degrees in a linear molecule. The deviation of the optimal angle is because of the repulsion of two electron pairs that are the only ones in the sulfur atom. The lone electron pairs are more repellent than electrons that bond because they aren’t constrained by a neighboring atom. Thus, they tend to take up more space and result in the bond angle being different away from the perfect linear geometric.

Factors Affecting The Bond Angle Of H2s

The bond angle in H2S may be affected by various factors, including the electronegativity and size of the atoms that form the bond. The sulfur atom is larger than oxygen, which results in the bond angle of H2S being more in comparison to the one of H2O. Furthermore, sulfur has a lower electronegativity compared to oxygen, meaning that hydrogen bonding electrons that are found in H2S will be less attracted by sulfur than bonding electrons of H2O are attracted by oxygen. This leads to stronger bonds for H2S which makes the bond angle greater than the one in H2O.

Another element that may alter how H2S bonds are affected is the existence of other molecules and ions within the vicinity. For instance, when H2S is surrounded by other molecules and ions having a negative charge, and experiences an increased attraction to these ions, causing the angle of the bond to become smaller. In contrast, if H2S is in the presence of different molecules, or even ions that have positively charged and a positive charge, it will experience a lower attraction to them, which causes the angle of the bond to become greater.

In the end, the bond angle for H2S is approximately 92 degrees, which is considerably lower in comparison to the perfect angle that is required for linear geometries. Its deviation from ideal angles results from the attraction between two electron pairs that are the only ones in the sulfur atom. The bond angle in H2S is influenced by many factors, such as the electronegativity and size of the atoms in the bond and the presence of different molecules or ions in the vicinity. Knowing the bond angle of H2S is essential to comprehend its chemical properties and behavior.

Molecular Geometry & Hybridization Of H2s

Hydrogen sulfur (H2S) is an organic compound composed consisting of 2 hydrogen atoms as well as a sulfur atom. It is a colorless and flame-resistant gas with a strong scent, similar to the smell of eggs that have gone rotten. In this article, we’ll examine the molecular geometry and the hybridization of H2S.

Molecular Geometry Of H2s

The molecular structure of H2S is determined by using this theory. Valence Shell Electron Pair Repulsion (VSEPR) theory. According to this theory, electron pairs inside the inner valence shells of atoms oppose each other, and this repels the geometry of the molecular. The electron pairs could be bonding pairs that are shared by two atoms or lone pairs that are not associated with another atom.

For H2S, sulfur atoms have six electrons of valence, two of which are shared by each hydrogen atom. The other two are lone pairs. The VSEPR theory suggests that the two lone pairs of the sulfur atom would repel the bonding pair, causing the molecule to exhibit bent shapes. The bent shape results from electron pairs trying to be from one of their counterparts as far as possible.

Hybridization Of H2s

Hybridization is mixing orbitals in the atomic form to create new orbital hybrids. The hybrid orbitals come in different sizes and energy levels and can hold electrons in bonds. In H2S, the sulfur atom gets hybridized to form sp3.

To comprehend the hybridization of H2S, it is necessary to look at the valence shell of the sulfur atom. The sulfur atom is composed of six electrons in its valence shell, and to create bonding with hydrogen molecules, it requires two electrons. The remaining four valence electrons in sulfur are organized in two pairs.

The Hybridization Of The Sulfur Atom Occurs As Follows:

The sulfur atoms 3p orbital and 3s orbital combine to form four sp3 sp3 hybrid orbitals.

The four SP3 hybrid orbitals are set in a tetrahedral configuration near sulfur, with two single electron pairs taking up one of the orbitals and the two hydrogen atoms taking up two.

The sulfur orbitals that are hybrid overlap with hydrogen 1s orbitals, forming Sigma bonds between hydrogen and sulfur molecules.

The sp3 hybridization in H2S permits it to form four sigma bonds: two of which are hydrogen atoms and two that are lone electron pairs. The bond angle between two hydrogen atoms found in H2S is 92 degrees, as discussed previously.

In the end, the molecular structure that H2S has is bent, which is why the hybridization sulfur atom is called sp3. The best form of the molecular structure is the result of electron pairs fighting to be as far from each other as they can, according to the theory of VSEPR. The sp3 hybridization process in H2S lets it create four sigma bonds: hydrogen atoms and two with lone pairs of electrons. Understanding the molecular structure and hybridization of H2S is essential to know its properties and behavior.


Hydrogen Sulfide (H2S) is among the most frequently occurring sulfur compounds in the natural environment. It is a chemical that can be absorbed through the skin, eyes, mouth, and eyes. It is a danger to those who are prone to or suffer from specific health conditions. Exposure to high levels of H2S may cause discomfort in the skin, headaches as well as loss of appetite, weight loss, and even death or coma.

The hydrogen atoms of H2S form bonds that are formed with sulfur. They share electrons in order to make them stable. Sulfur atoms are more electronegative than hydrogen atoms and exert a greater force on electrons shared.

As a result, the hydrogen atoms get drawn toward the sulfur atom. This creates a dipole moment between the bonds of the atoms. The added force between intermolecular forces raises the temperatures of the water and is responsible for certain types of biogenic sulfide sulfur-sulfide corrosion found in the environment.

Nonpolar Information:

H2S is considered nonpolar due to the electronegativity difference between bond atoms being less than 0.5. The two atoms which form those bonds have electronegativity values that are 2.20 and 2.58 and an average difference of 0.38 units. This is lower than the 0.5 unit threshold to be considered a polar bond; however, it can still trigger an electric dipole within the molecule.

A dipole moment refers to the amount of charge imposed on an atom canceled out because of its symmetrical arrangement and equal charge distribution. It is the primary aspect to consider when determining if the molecule is polar.

In addition to having a dipole moment, the molecule’s structure can affect its Polarity. This is especially true for molecules such as CO2 and H2S with an angled molecular structure.

Furthermore, the two lone pair electrons of the central sulfur atoms repel one another, and the close electrons in bonded pairs. Repulsion causes electron pairs to shift to the position in which they experience the least amount of repulsion. This is why the final design of molecular geometry is an elongated or V-shaped structure.

It is crucial to realize the molecular geometry of a molecule and electron geometries are different. Therefore, it is necessary to consider the lone pair and bond pair in determining the molecular shape of a molecule.

For the electron structure, a molecule could be either octahedral or tetrahedral, about the number of valence electrons within the molecule. The electrons in lone pairs are also. The electrons of the lone pair are in an encapsulated orbital called the p (1b11) orbital, while the bond pair electrons are in an sp pure (3a11) orbital.

When you are determining the Polarity of a molecule, be aware that a molecule’s sole pair electrons are located in the sp3 while the bond pair electrons are in orbitals p. Thus, a molecule that contains eight valence electrons is a tetrahedral one and one with six valence electrons is an octahedral molecular.

H2s Vsepr Shape


Hydrogen sulfur (H2S) is an organic compound comprising two hydrogen atoms and the sulfur atom. Their arrangement within space defines the molecular shape of H2S. In this article, we’ll go over the VSEPR shape of H2S.

VSEPR Theory:

It is believed that the VSEPR (Valence Shell Electron Pair Repulsion) theory is used to determine the form of a molecule based on the arrangement and configuration of its molecules and the electron pairs that are the only ones. Based on this theory, the electron pairs within the shells of valence in an atom will repel one another and seek to lessen the repulsion by choosing a specific molecular structure.

Steps To Determine The Vsepr Shape Of H2s:

  • Find your Lewis structure: The first step to finding out how to determine the VSEPR structure of the H2S is drawing the Lewis structure. This Lewis shape of the H2S is composed of hydrogen atoms bonded to the central sulfur atom, which has two pairs of electrons in the sulfur atom.
  • Check your Electron Pairs: Next, determine the number of pairs of electrons in the valence in sulfur. For H2S, it has four pairs of electrons: Two bonding pairs and two pairs of lone electrons.
  • Find out your Electron Pair Geometry: By calculating the electron pair count, you can identify how H2S’s electron-pair geometry is constructed. For H2S, its electron-pair geometry can be described as trihedral.
  • Find your Molecular Geometry: The final step is to identify the molecular shape of H2S. In order to do this, we must take into consideration the effects of lone pairs on geometry. Two lone pairs on the sulfur atom exert a greater repulsive force than pairings that bond, pushing hydrogen atoms closer. In the end, the molecule takes on a bent or V-shaped shape.

Vsepr Shape Of H2s:

By the VSEPR theory, The shape of H2S has been twisted or V-shaped. Its electron-pair geometry is trihedral; however, the molecular structure is bent because of two single pairs of sulfur atoms. Its bonding angle with two hydrogen atoms of H2S is 92.5 degrees. That’s a bit lower than the ideal angle, which is 109.5 degrees.


The VSEPR theory can be a helpful method to predict the shape of molecules based on how their atoms are arranged as well as electron pairs. Based on this theory, it is possible to identify the electron-pair geometry and the molecular structure of H2S. Its electron-pair geometry is tetrahedral, and the molecular structure has a V shape or is bent due to being surrounded by two single pairs of sulfur atoms. Understanding the VSEPR structure of H2S is crucial in determining its chemical and physical properties, which include the boiling temperature, its solubility, and its reactivity.


What is the bond angle of H2S hybridization?

The bond angle for H2O is 104.5, and the bond angle for H2S is 92.1.

Are the bonds in H2S polar or nonpolar?

Because of its nonpolar H-S bonds, hydrogen sulphide is nonpolar. Hydrogen and sulphur form non-polar bonds because their EN differences are 0.4. The entire molecule is non-polar since there are no polar bonds present, despite the fact that it has an asymmetrical molecular geometry.

What is the hybridization shape of H2S?

Hybridization of H2S with sp3; V-shaped molecule.

What is the geometry and bond angle of H2S?

Hybridization of H2S with sp3; V-shaped molecule.

Why H2S has no hybridization?

What is this? Sulfur, the core atom, is in the third period, has two unpaired electrons, and lacks a positive charge. Moreover, hydrogen has an electronegativity of 2.1. This explains why H2S does not have hybridization.

Why is H2S bond angle 90?

In H2S, sigma bonds are created between the H atoms and two of the three orthogonal 3p orbitals, which have an octahedral geometry. Hence, the bond angle in H2S is around 90 degrees (92).

Why is H2S non polar?

Because it is entirely composed of nonpolar $ H – S $ bonds, the hydrogen sulphide molecule as a whole is nonpolar. The absence of polar connections makes the molecule non-polar overall, despite its asymmetrical chemical form. Note: Electronegativity largely determines the many types of covalent bonding.
