Introduction

Hydrogen sulfide ($H_2S$) is a colorless, highly toxic, and flammable gas with a characteristic "rotten egg" odor. It is composed of two hydrogen atoms and one sulfur atom, making it a simple diatomic molecule. In this article, we will delve into the bonding present in hydrogen sulfide and explore the different types of bonds that can exist in molecules.

What is a Bond?

A bond is a chemical bond that holds two or more atoms together in a molecule. There are several types of bonds, including ionic, covalent, and metallic bonds. In this discussion, we will focus on the covalent bond, which is the type of bond present in hydrogen sulfide.

Covalent Bond

A covalent bond is a type of chemical bond that involves the sharing of electron pairs between two or more atoms. In a covalent bond, the atoms share one or more pairs of electrons to achieve a stable electronic configuration. Covalent bonds can be either polar or nonpolar, depending on the difference in electronegativity between the atoms involved.

Polar Covalent Bond

A polar covalent bond is a type of covalent bond where the electrons are not shared equally between the two atoms. This occurs when there is a significant difference in electronegativity between the atoms involved. In a polar covalent bond, the atom with higher electronegativity pulls the shared electrons closer to itself, resulting in a partial positive charge on the other atom.

Nonpolar Covalent Bond

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms. This occurs when there is little to no difference in electronegativity between the atoms involved. In a nonpolar covalent bond, the atoms share the electrons equally, resulting in no partial charges on either atom.

Hydrogen Sulfide ($H_2S$) Bonding

Hydrogen sulfide ($H_2S$) is composed of two hydrogen atoms and one sulfur atom. The bonding in hydrogen sulfide is a combination of covalent and polar covalent bonds. The sulfur atom is more electronegative than the hydrogen atoms, resulting in a polar covalent bond between the sulfur and hydrogen atoms.

Electronegativity

Electronegativity is a measure of an atom's ability to attract electrons in a covalent bond. The higher the electronegativity of an atom, the more it will pull the shared electrons closer to itself. In hydrogen sulfide, the sulfur atom has an electronegativity of 2.58, while the hydrogen atom has an electronegativity of 2.20. This results in a significant difference in electronegativity between the sulfur and hydrogen atoms, making the bond between them polar covalent.

Polarity of the Bond

The polarity of a bond is a measure of the degree to which the bond is polar. In hydrogen sulfide, the bond between the sulfur and hydrogen atoms is polar, with the sulfur atom having a partial negative charge and the hydrogen atom having a partial positive charge.

Conclusion

In conclusion, the type of bond present in hydrogen sulfide ($H_2S$) is a polar covalent bond. The sulfur atom is more electronegative than the hydrogen atoms, resulting in a polar covalent bond between the sulfur and hydrogen atoms. This bond is characterized by a partial positive charge on the hydrogen atom and a partial negative charge on the sulfur atom.

Answer

The correct answer is D. polar covalent.

Q: What is the type of bond present in hydrogen sulfide ($H_2S$)?

A: The type of bond present in hydrogen sulfide ($H_2S$) is a polar covalent bond.

Q: Why is the bond between the sulfur and hydrogen atoms in hydrogen sulfide ($H_2S$) polar?

A: The bond between the sulfur and hydrogen atoms in hydrogen sulfide ($H_2S$) is polar because of the significant difference in electronegativity between the sulfur and hydrogen atoms. The sulfur atom has an electronegativity of 2.58, while the hydrogen atom has an electronegativity of 2.20.

Q: What is the polarity of the bond between the sulfur and hydrogen atoms in hydrogen sulfide ($H_2S$)?

A: The polarity of the bond between the sulfur and hydrogen atoms in hydrogen sulfide ($H_2S$) is characterized by a partial positive charge on the hydrogen atom and a partial negative charge on the sulfur atom.

Q: What is the difference between a polar covalent bond and a nonpolar covalent bond?

A: A polar covalent bond is a type of covalent bond where the electrons are not shared equally between the two atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other atom. A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms, resulting in no partial charges on either atom.

Q: What is the significance of electronegativity in determining the type of bond between two atoms?

A: Electronegativity is a measure of an atom's ability to attract electrons in a covalent bond. The higher the electronegativity of an atom, the more it will pull the shared electrons closer to itself. This can result in a polar covalent bond if the difference in electronegativity between the two atoms is significant.

Q: Can hydrogen sulfide ($H_2S$) form ionic bonds?

A: No, hydrogen sulfide ($H_2S$) does not form ionic bonds. Ionic bonds are formed between two atoms with a significant difference in electronegativity, resulting in the transfer of electrons from one atom to another. In hydrogen sulfide, the sulfur and hydrogen atoms share electrons in a covalent bond, rather than transferring electrons in an ionic bond.
