Chapter 20, Problem 9PP

Interpretation Introduction

Interpretation:

The formation of ${\text{NO}}^{\text{+}}$ ions in an aqueous solution of ${\text{NaNO}}_2$ and $\text{HCl}$ is to be shown, mechanism for $p-$ nitrosation of N, N-dimethylaniline is to be written and the reason for the fact that tertiary aromatic amines and phenols undergoes C-nitrosation reaction whereas most of the benzene derivatives do not undergoes C-nitrosation reaction is to be explained.

Concept Introduction:

▸ The nitrosonium ion is ${\text{NO}}^{\text{+}}$, in which a nitrogen atom is attached to an oxygen atom with a bond order of three and the ion carries one unit positive charge.

▸ The nitrite ion has the chemical formula ${\text{NO}}_{\text{2}}{}^{-}$. It is a symmetric anion with equal $\text{N}-\text{O}$ bond lengths.
