The correct order of basicities of the following compounds is

Answer

B

Explanation

The conjugate acid (i) obtained by addition of a proton to 1 is stabilized by two equivalent resonance structures and hence compound (1) is the most basic. Further, `2^(@)` amines are more basic than `1^(@)` amines while amides are least basic due to delocalization of lone pair of electrons of N over the C=O group. thus, the order: 1gt3gt2gt4, i.e., option (b) is correct.
