Text Solution

Verified by Experts

(a) In the esterification reactino an acid reacts with alcohol in the presence of conc. `H_(2)SO_(4)` to form an ester with a leasant or fruity smell. For example,
`underset("Ethanoic acid")(CH_(3)COOH)+underset("Ethanol")(C_(2)H_(5)OH)overset(H_(2)SO_(4)(conc.))tounderset("Ethyl ethanoate (ester)")(CH_(3)COOC_(2)H_(5))+H_(2)O`
Saponification is quite different from esterification because in this case an ester reacts with an alkali
(NaOH or KOH) to form salt of acid and alcohol. for example.
`underset("Ethyl ethanoate")(CH_(3)COOC_(2)H_(5))+NaOHtounderset("Sod. ethanoate")(CH_(3)COONa)+underset("Ethanol")(C_(2)H_(5)OH)`
(b).
