4-acetyl biphenyl

Ten nonbonding electrons and 14 bonding electrons are in acetyl chloride.

Synthesis of acetyl chloride via the reaction of acetic acid with sulphuric acid

This is an example of a Friedel-Crafts acylation. One hydrogen from the benzene is replaced by the acetyl portion of the acetyl chloride and the hydrogen and chloride from the benzene and acetyl chloride respectively combine to form HCl. Please see the link.

The nucleophilic nitrogen attacks the carbonyl carbon of acetyl chloride. HCl gas is released and acetyl glycine is formed.
