Vedclass · Answer

(B) Arylamines are generally weaker bases than ammonia and aliphatic amines due to the resonance effect,which delocalizes the lone pair of electrons on the nitrogen atom into the benzene ring.Aliphatic amines are stronger bases than ammonia due to the electron-donating inductive effect ($+I$ effect) of the alkyl groups.Among aliphatic amines,$(CH_3)_2NH$ ($2^{\circ}$ amine) is a stronger base than $CH_3NH_2$ ($1^{\circ}$ amine) in the gas phase or non-polar solvents due to the greater inductive effect of two methyl groups.Therefore,the correct decreasing order of basic strength is: $(CH_3)_2NH > CH_3NH_2 > NH_3 > C_6H_5NH_2$.
