ACYL CHLORIDES: REACTIONS WITH WATER, ALCOHOLS AND
PHENOLS
1. a) You would get a very vigorous reaction (less so in the case of phenol) producing steamy fumes.

(In the final case, it doesn’t matter where you have drawn the benzene ring relative to the oxygen.
It would make just as much sense to move the benzene ring and its attaching bond so that it was
sticking out at the right-hand side rather than hanging down. You will find the other version on the
Chemguide page.)
2. a)
COOH

b) Acylation means substituting an acyl group, RC=O, into another molecule. R is a hydrocarbon
group. Ethanoylation is a particular example of acylation where a CH3C=O group (an ethanoyl
group) is substituted into another molecule.
