Chapter 7, Problem 7.65QP

Interpretation Introduction

Interpretation:

The hybridization of the central N atom in the azide ion (${\text{N}}_{\text{3}}{}^{\text{-}}$ ) has to be shown.

Concept introduction:

Hybridization: The concept of mixing atomic orbitals into new hybrid orbitals.

There are few steps to determine hybridization of an atom in a molecule.

• Count the number of atoms connected to the atom wish to calculate hybridization.
• Count the number of lone pairs attached to the atom wish to calculate hybridization.
• Sum these two numbers together to get final answer.
• If it is 4, the atom present in ${\text{sp}}^{\text{3}}$ hybridization.
• If it is 3, the atom present in ${\text{sp}}^2$ hybridization.
• If it is 2, the atom present in $\text{sp}$ hybridization.
• If it is 1, probably hydrogen.
