Answer:
esterification reaction in which an alcohol and a carboxylic acid react to form an ester
Explanation:
Esterification involves the reaction of an alcohol and a carboxylic acid to form an ester. This is an analogue of amidation which involves the reaction of a carboxylic acid with an amine to form an amide.
The relationship between the two reactions is that in both cases, the carbonyl (CO) group of the carboxylic acid is maintained and then bonded to a new moiety in the product. Water is formed in both reactions.
Hence, for esterification;
RCOOH + ROH ------> RCOOR + H2O
For amidation;
RCOOH + RNH2 -------> RCONHR + H2O
