Q2. Among below _______ is the more basic amine? 1. Aniline 2. Para methyl aniline 3. CH3NH2 4. (CH3)2NH 5. (CH3)3N `````````````````````````````````````````` ` ` ` ` ` ` Answer Option 4 Basicity is occurred because the lone pair on N atom can accept a proton. So anything which increased the electron density on N atom will increase the basicity and vice versa. Aromatic amines are less basic than aliphatic amines since the lone pair on N atom is used to activate benzene ring in aromatic amines. Methyl group can donate electrons to the benzene ring and will help to remain the lone pair of N atom on itself. So it is more basic than aniline. Considering aliphatic amines, the order of basicity is 3 °
