Vedclass · Answer

(C) The basic strength of amines in aqueous solution is determined by a combination of inductive effect,solvation effect (hydrogen bonding),and steric hindrance. For ethyl-substituted amines,the order is $(CH_3CH_2)_2NH > (CH_3CH_2)_3N > CH_3CH_2NH_2 > NH_3$. $H_2N-NH_2$ (hydrazine) is a weaker base than $NH_3$ due to the electron-withdrawing effect of the second amino group. Thus,the overall order is $H_2N-NH_2 < NH_3 < (CH_3CH_2)_3N < CH_3CH_2NH_2 < (CH_3CH_2)_2NH$.

The correct order of basic nature in aqueous solution for the bases $NH_3$,$H_2N-NH_2$,$CH_3CH_2NH_2$,$(CH_3CH_2)_2NH$,and $(CH_3CH_2)_3N$ is $:$
