(a) Explain esterification reaction between acetic acid and ethyl alcohol as example.
(b) Boiling point of alcohol is greater than the boiling point of hydrocarbons of coparable molar masses, Why?
(c ) What is the effect of `-NO_(2)` group on the acidic strength of phenol?Give reason.

Text Solution

Verified by Experts

(a) When acetic acid is heated with ethyl alcohol in the presence of conc.`H_(2)SO_(4)`, ethyl acetate is formed.
`CH_(3)COOH + C_(2)H_(5)OH overset("conc. "H_(2)SO_(4))to CH_(3)COOC_(2)H_(5) + H_(2)O`
(b) Hydrogen bonding
(c ) Acidic strength of phenol increases. Because -`NO_(2)` is electron withdrawing group.
