प्रश्न
Describe one reaction of a carboxylic acid.
उत्तर
Ethanoic acid is a carboxylic acid which when reacts with ethanol (alcohol) produces sweet smelling ester. The process in which the carboxylic acid reacts with alcohol, in the presence of a catalyst, to form an ester is called esterification.
The chemical equation for the above reaction is as follows:
`CH_3 COOH +_2 H_5 OH` 
`CH_3 COOC_2 H_5 + H_2O`
