Chapter 16.3, Problem 5P
Interpretation Introduction

a)

Organic Chemistry, Chapter 16.3, Problem 5P , additional homework tip  1

Interpretation:

Whether ethyl chloride is expected to undergo Friedal-Crafts reaction with or without rearrangement is to be stated and explained.

Concept introduction:

Friedal-Crafts reaction is an electrophilic substitution reaction in which an aromatic compound reacts with an alkyl chloride in the presence of AlCl3 to produce an alkylbenzene. The electrophile in this reaction is an alkyl carbocation. The skeletal rearrangement of the alkyl carbocation electrophile either through a hydride shift or alkyl shift (particularly when a primary alkyl halide is used) can lead to the formation of rearranged products also in this reaction.

To state and explain:

Whether ethyl chloride is expected to undergo Friedal- Crafts reaction with or without rearrangement.

Interpretation Introduction

Interpretation:

Whether chlorocyclohexane is expected to undergo Friedal Crafts reaction with or without rearrangement is to be stated and explained.

Concept introduction:

Friedal-Crafts reaction is an electrophilic substitution reaction in which an aromatic compound reacts with an alkyl chloride in the presence of AlCl3 to yield an alkylbenzene. The electrophile in this reaction is an alkyl carbocation. The skeletal rearrangement of the alkyl carbocation electrophile either through a hydride shift or alkyl shift, particularly when a primary alkyl halide is used, can lead to the formation of rearranged product also in this reaction.

To state and explain:

Whether chlorocyclohexane is expected to undergo Friedal-Crafts reaction with or without rearrangement.
