Vedclass · Answer

(C) In aqueous solution,the basic strength of aliphatic amines depends on the combined effect of inductive effect,solvation effect,and steric hindrance. The order for methyl-substituted amines is $(CH_3)_2NH > CH_3NH_2 > (CH_3)_3N$. Comparing this with $NH_3$ and aniline $(C_6H_5NH_2)$: $1$. $(CH_3)_2NH$ $(V)$ is the most basic due to the $+I$ effect and favorable solvation. $2$. $CH_3NH_2$ $(IV)$ is next. $3$. $(CH_3)_3N$ $(II)$ is less basic than $CH_3NH_2$ and $(CH_3)_2NH$ due to steric hindrance in the aqueous phase. $4$. $NH_3$ $(III)$ is less basic than the aliphatic amines. $5$. $C_6H_5NH_2$ $(I)$ is the least basic because the lone pair on nitrogen is delocalized into the benzene ring. Thus,the correct order is $V > IV > II > III > I$.

The order of basic strength of the following in aqueous solution is
$I$. $C_6H_5NH_2$
$II$. $(CH_3)_3N$
$III$. $NH_3$
$IV$. $CH_3NH_2$
$V$. $(CH_3)_2NH$
