Question

Give reason for the following:

(i) Ethanoic acid is more acidic than ethanol.

(ii) Aniline is less basic than ammonia.

Answer 1

(¡) Ethanoic acid is more acidic than ethanol because anion of ethanoic acid is resonance stabilized whereas anion of ethanol not.

(ii) In case of aniline the lone pair are involved in resosnace structure so availability of lone pair of electron is less as compared to ammonia and thus acts as less basic than ammonia.
