Vedclass · Answer

(C) In aqueous solution,the basicity of aliphatic amines depends on the inductive effect,solvation effect,and steric hindrance. For ethyl-substituted amines,the order of basicity is $(C_2H_5)_2NH > C_2H_5NH_2 > (C_2H_5)_3N$. $NH_3$ is less basic than these aliphatic amines. $C_6H_5NH_2$ (aniline) is the least basic due to the delocalization of the lone pair of electrons on the nitrogen atom into the benzene ring. Therefore,the correct increasing order is $C_6H_5NH_2 < NH_3 < (C_2H_5)_3N < C_2H_5NH_2 < (C_2H_5)_2NH$.

The correct order of increasing basicity for the given compounds in aqueous solution is:
