Chapter 23, Problem 23.34P

Interpretation Introduction

(a)

Interpretation:

The curved-arrow notation for the generation of nitrosyl cation, ${}^{\text{+}}\ddot{\text{N}}\text{=}\underset{¨}{\ddot{\text{O}}}$, from ${\text{HNO}}_{\text{2}}$ is to be stated.

Concept introduction:

Electrophilic aromatic substitution reaction involves the substitution of an electrophile on an aromatic ring. The $\text{π-}$ bonds of an aromatic ring makes it electron rich which attracts an electron deficient electrophile towards itself and a substitution reaction takes place.

Interpretation Introduction

(b)

Interpretation:

The curved-arrow mechanism for the electrophilic aromatic substitution reaction of $N,N\text{-dimethylaniline}$ with ${\text{HNO}}_{\text{2}}$ and $\text{HCl}$ is to be stated.
