Vedclass · Answer

(A) In an aqueous medium,the basic strength of amines is determined by a combination of three factors: inductive effect,solvation effect,and steric hindrance.$1$. The inductive effect ($+I$ effect) of methyl groups increases the electron density on the nitrogen atom,making it more basic.$2$. The solvation effect stabilizes the protonated amine cation through hydrogen bonding with water molecules. More substituted cations are less stabilized due to steric hindrance.$3$. For methyl-substituted amines,the combined effect results in the following order of basicity: $Me_2NH > MeNH_2 > Me_3N > NH_3$.

The correct order of basic strength of methyl-substituted amines in an aqueous medium is:
