Ammonia and amines can act as nucleophiles in attacking the positive centres in
molecules such as ethanoyl chloride, CH,COCl, and benzoyl chloride,
C6HSCOC1. For example, ammonia reacts very vigorously with ethanoyl
chloride, forming ...

with a C–O bond length of 1.108 ̊A, notably shorter than the C–O bond length in
ethanoyl chloride at 1.187 ̊A. Once the chloride ion has departed, there are only
two atoms or groups around the carbonyl carbon in [CH3CO]+, the methyl ...

A-Level Study Guide Chemistry (Higher 2):
5 Ethanoyl chloride undergoes hydrolysis (nucleophilic substitution) more
readily than chloroethane because the C atom carries a considerably larger
positive charge since it is attached to two strongly electronegative atoms (O and
Cl).
