Vedclass · Answer

(A) The basic strength of amines in aqueous solution depends on the combined effect of inductive effect,solvation effect,and steric hindrance. For methyl-substituted amines,the order of basic strength is $(CH_3)_2NH > CH_3NH_2 > (CH_3)_3N > C_6H_5NH_2$.Since $pK_b = -\log K_b$,a higher $K_b$ value corresponds to a smaller $pK_b$ value.Therefore,$(CH_3)_2NH$ (dimethylamine) has the highest basic strength and consequently the smallest $pK_b$ value.$C_6H_5NH_2$ (aniline) is the least basic due to the resonance of the lone pair with the benzene ring.

Considering the basic strength of amines in aqueous solution,which one has the smallest $pK_b$ value?
