Draw a Lewis structure for diimide, H—N═N—H. Then, using valence bond theory, describe the bonding in this compound. What orbitals overlap to form the bond between nitrogen atoms in this compound?

Interpretation Introduction

Interpretation:

Lewis structure of diimide should be drawn then using valence bond theory bonding in the compound and the orbitals overlap to form the bond between nitrogen atoms in this compound should be determined and described.

Concept Introduction:

Valance bond (VBT) theory: This theory explain a chemical bonding theory that explains the bonding between two atoms is caused by the overlap of half-filled atomic orbitals. The two atoms share each other's unpaired electron to form a filled orbital to form a hybrid orbital and bond together.

Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.

It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have 8 electrons in its outer shell.

Explanation

Bonding in the compound can be explained using Valence bond theory as follows,

The diimide (structure is shown below), the electron-pair geometry around both the N atoms is in bend structure. Then we assign sp2 hybridization to each atoms and the N=N bond is formed by sidewise overlap of pi-orbital orbital on these atoms. Each N-N bond is formed by overlap of a sp2 orbital with a hydrogen 1s orbital and the N-H bond if formed by overlapping of nitro
