Vedclass · Answer

(D) The basic strength of amines is inversely proportional to their $pK_{b}$ values.$1$. Aniline $(A)$ is the least basic due to resonance,so it has the highest $pK_{b}$ value: $9.38$ $(III)$.$2$. Among aliphatic amines,the basicity order in aqueous solution is determined by inductive effect,solvation,and steric hindrance. For ethylamines,the order is: $N$-Ethylethanamine ($C$,secondary) > $N,N$-Diethylethanamine ($D$,tertiary) > Ethanamine ($B$,primary).$3$. Corresponding $pK_{b}$ values are:- $C$ ($N$-Ethylethanamine): $3.00$ $(II)$- $D$ ($N,N$-Diethylethanamine): $3.25$ $(I)$- $B$ (Ethanamine): $3.29$ $(IV)$Thus,the correct matching is: $A-III, B-IV, C-II, D-I$.
