प्रश्न
Account for the following.
pKb of aniline is more than that of methylamine.
उत्तर
In aniline, the lone pair of electrons on the N-atom is delocalized over the benzene ring. As a result electron density on the nitrogen decreases. In contrast in CH3NH2, the +I effect of CH3 increases the electron density on the N-atom. Therefore, aniline is a weaker base than methylamine and hence its pKb value is more than that of methyl amine.
