Vedclass · Answer

(B) Step $1$: In the aqueous phase, the basicity of aliphatic amines depends on the combined effect of the inductive effect $(+I)$, solvation effect, and steric hindrance.Step $2$: For methyl-substituted amines, the order is $(CH_3)_2NH > CH_3NH_2 > NH_3$.Step $3$: $C_6H_5NH_2$ (aniline) is the least basic because the lone pair on the nitrogen atom is involved in resonance with the benzene ring, making it less available for protonation.Step $4$: Combining these, the decreasing order of basic strength is $(CH_3)_2NH > CH_3NH_2 > NH_3 > C_6H_5NH_2$.

Identify the correct decreasing order of the basic strength of the following amines in the aqueous phase: $CH_3NH_2$, $(CH_3)_2NH$, $C_6H_5NH_2$, and $NH_3$.
