Vedclass · Answer

(A) The basicity of amines in an aqueous solution depends on three factors: inductive effect ($+I$ effect),solvation effect (hydrogen bonding),and steric hindrance.For methyl-substituted amines,the secondary amine $(CH_3)_2NH$ is the most basic due to the optimal balance between the $+I$ effect of two methyl groups and the solvation of the protonated amine.The tertiary amine $(CH_3)_3N$ is less basic than the secondary amine due to steric hindrance,which hinders the approach of the proton.The primary amine $CH_3NH_2$ is the least basic among these three because it has only one methyl group to increase the electron density on the nitrogen atom.Therefore,the correct order of basicity is: $(CH_3)_2NH > (CH_3)_3N > CH_3NH_2$.
