Chapter 17.SE, Problem 30MP

Interpretation Introduction

a)

Interpretation:

The complete mechanism for the conversion of 3⁰ alcohol given to 3⁰ alkyl halide by treating with HCl involving two cationic intermediates is to be proposed.

Concept introduction:

Alcohols get protonated in the presence of strong acids. The protonated intermediate will lose a molecule of water to yield a carbocation. The nucleophilic attack by the halide ion will lead to the formation of the alkyl halide.

To propose:

The complete mechanism for the conversion of 3⁰ alcohol given to 3⁰ alkyl halide by treating with HCl involving two cationic intermediates.

Interpretation Introduction

b)

Interpretation:
