Dimethylamine

Vedclass · Answer

(D) Aromatic amines are less basic than aliphatic amines. Among aliphatic amines,the order of basicity in aqueous solution is $2^{o} > 1^{o} > 3^{o}$ due to a combination of inductive effect,solvation effect,and steric hindrance. In $3^{o}$ amines (Trimethylamine),the steric hindrance of three alkyl groups makes the approach and bonding of a proton relatively difficult. Aniline is much less basic than aliphatic amines because the lone pair of electrons on the nitrogen atom is involved in resonance with the benzene ring. Therefore,Dimethylamine ($2^{o}$ aliphatic amine) is the strongest base among the given choices. $	herefore$ The correct order of basic strength is $	ext{Dimethylamine} > 	ext{Methylamine} > 	ext{Trimethylamine} > 	ext{Aniline}$.

Which one of the following is the strongest base in aqueous solution?
