Chapter 22, Problem 22.55P

Interpretation Introduction

Interpretation:

Compounds A-I in the given synthesis scheme are to be identified

Concept introduction:

Nitration is the aromatic electrophilic substitution reaction in the presence of concentrated nitric acid and concentrated sulfuric acid. In this reaction, nitronium ion ${\text{NO}}_{\text{2}}^{\text{+}}$ are attached to the aromatic ring and acts as an electrophile. Reagent $\text{Fe}$ and $\text{HCl}$ is converted nitrobenzene to aniline. Benzene undergoes aromatic electrophilic substitution with molecular bromine in the presence of a Lewis acid such as ${\text{FeBr}}_3$ to yield bromobenzene. ${\text{NaBH}}_{\text{4}}$ is a reducing agent that is used to convert the carbonyl carbon to alcohol.
