Question

Define esterification reaction with the help of chemical equations

Answer 1

Esterification reaction : Esters are most commonly formed by reaction of an acid and an alcohol. Ethanoic acid reacts with absolute ethanol in the presence of an acid catalyst to give an ester -

CH3 COOH + CH3 CH2OH ------
( Ethanoic acid ) ( Ethanol)
CH3 C= O OCH3 CH3
(ester)

Answer 2

The reaction of carboxylic acid with alcohol forms an ester. For example, ethanol reacts with ethanoic acid in the presence of an acid catalyst to give sweet smelling substance, i.e. an ester which in this case will be ethylethanoate. This reaction is known as esterification reaction.
