Give reasons :
(a) Methylamine is a stronger base than ammonia.
(b) Reactivity of `-NH_(2)` groups gets reduced in acetanilide.

Text Solution

Verified by Experts

(a) It is because methyl group is electron releasing and increases electron density on .N..
(b) It is because `CH_(3)-overset(overset(O)(||))(C)-`group is electron withdrawing. The lone pair of electrons is involved in conjugation with the carbonyl group, thus decreasing electron density on nitrogen.
