Vedclass · Answer

(A) The basicity of amines in the aqueous phase depends on the inductive effect,solvation effect,and steric hindrance.$1$. $C_6H_5NH_2$ (Aniline) is the least basic because the lone pair on the nitrogen atom is involved in resonance with the benzene ring.$2$. Among aliphatic amines,the order is $(CH_3)_2NH > CH_3NH_2 > (CH_3)_3N$.$3$. $(CH_3)_2NH$ is the most basic due to the combined effect of the $+I$ effect of two methyl groups and favorable solvation.$4$. $(CH_3)_3N$ is less basic than $(CH_3)_2NH$ and $CH_3NH_2$ due to significant steric hindrance.Therefore,the correct order is $C_6H_5NH_2 < (CH_3)_3N < CH_3NH_2 < (CH_3)_2NH$,which corresponds to $(i < iv < ii < iii)$.

The correct order of basicity in amines is:
$(i)$ $C_6H_5NH_2$
$(ii)$ $CH_3NH_2$
$(iii)$ $(CH_3)_2NH$
$(iv)$ $(CH_3)_3N$
