Question

The reason for higher pkb value of aniline compared to that of methylamine is

Answer 1

Explanation:

In aniline, the lone pair of electrons on the N atom is delocalised over the benzene ring. ... Therefore, aniline is a weaker base than methylamine. Hence, its pKb value is higher than that of methylamine. (ii) Being more basic than water, methylamine accepts a proton from water-liberating OH− ions.

Answer 2

HERE IS YOUR ANSWER

(i) In aniline, the lone pair of electrons on the N atom is delocalised over the benzene ring. ... Therefore, aniline is a weaker base than methylamine. Hence, its pKb value is higher than that of methylamine.

(ii) Being more basic than water, methylamine accepts a proton from water-liberating OH− ions.
