Statement-$I$ is correct,but statement-$II$ is not correct

Vedclass · Answer

(C) Statement-$I$ is correct: $CH_3NH_2$ is more basic than $NH_3$ due to the electron-donating $+I$ effect of the methyl group. $C_6H_5NH_2$ (aniline) is less basic than $NH_3$ because the lone pair on nitrogen is delocalized into the benzene ring via resonance.Statement-$II$ is incorrect: In the aqueous phase,the basicity of ethyl-substituted amines is governed by a combination of inductive effect,solvation effect,and steric hindrance. The correct order for ethylamines is $(C_2H_5)_2NH > C_2H_5NH_2 > (C_2H_5)_3N$ (for $pK_b$ values) or $(C_2H_5)_2NH > C_2H_5NH_2 > (C_2H_5)_3N$ in terms of basic strength. The provided order $(C_2H_5)_3N > (C_2H_5)_2NH > C_2H_5NH_2$ is incorrect.

Consider the following statements:
Statement-$I$: $CH_3NH_2$ is more basic than $NH_3$,but $C_6H_5NH_2$ is less basic than $NH_3$.
Statement-$II$: The order of basic strength of ethyl-substituted amines in the aqueous phase follows the order $(C_2H_5)_2NH > (C_2H_5)_3N > C_2H_5NH_2$.
