Vedclass · Answer

(C) The basic strength of amines in aqueous solution depends on the combined effect of inductive effect,solvation effect,and steric hindrance. For ethyl-substituted amines,the order of basicity is $(C_2H_5)_2NH > (C_2H_5)_3N > C_2H_5NH_2$. $C_6H_5-NH_2$ (aniline) is the least basic among these because the lone pair on the nitrogen atom is involved in resonance with the benzene ring,making it less available for protonation. Therefore,the correct order is $(C_2H_5)_2NH > (C_2H_5)_3N > C_2H_5-NH_2 > C_6H_5-NH_2$.
