Chapter 23, Problem 23.54P

(a)

Interpretation Introduction

Interpretation:

The mechanism has to be proposed for the Ritter reaction.

Concept introduction:

Ritter reaction:

Alcohol reaction with hydrogen cyanide in the presence of sulphuric acid and water gives amide.

(b)

Interpretation Introduction

Interpretation:

The product should be identified when using acetonitrile instead of hydrogen cyanide followed by reduction using ${\text{LiAlH}}_{\text{4}}$.

Concept introduction:

Reduction: Aldehydes or ketones undergoing reduction by using reducing agent like LAH or NaBH₄ which provides alcohol.
