Methylamine

Vedclass · Answer

(C) The basicity of amines depends on the availability of the lone pair of electrons on the nitrogen atom and the stability of the conjugate acid formed.$1$. $CH_3NH_2$ (Methylamine) is a $1^{\circ}$ aliphatic amine. The $+I$ effect of the methyl group increases the electron density on the nitrogen atom,making it more basic than ammonia.$2$. $NH_3$ (Ammonia) has no alkyl group to increase electron density.$3$. $C_6H_5NH_2$ (Aniline) is less basic because the lone pair on nitrogen is involved in resonance with the benzene ring.$4$. $C_6H_5NHCH_3$ ($N$-methylaniline) is also less basic than aliphatic amines due to the resonance of the lone pair with the benzene ring.Therefore,$CH_3NH_2$ is the strongest base among the given options.

Which of the following compounds is the strongest base?
