Pkb of aniline is more than that of methyl amine.

Description : Pkb of aniline is more than that of methyl amine.

Last Answer : In aniline, the lone pair of electrons on the N-atom are delocalized over the benzene ring. As a result electron density on the nitrogen decreases. In contrast in CH2NH2 , + I effect of CH3 ... , aniline is a weaker base than methylamine and hence its Pkb value is higher than that of methylamine.
