Chapter 18, Problem 18.6P

Interpretation Introduction

(a)

Interpretation: The acid chloride which is needed to prepare the given ketones from benzene using a Friedel-Craft acylation is to be predicted.

Concept introduction: The Friedel-Craft acylation is a type of electrophilic substitution reaction. ${\text{AlCl}}_{\text{3}}$ is used as Lewis acid which ionizes the carbon-halogen bond of the acid chloride and forms a positively charged carbon electrophile which is resonance stabilized. Then the electrophile reacts with benzene.
