Q:	Aniline Aniline is a considerably weaker base than many aliphatic amines of comparable molecular weight because:

aniline exhibits much less steric hindrance than an aliphatic group of comparable size.

amines must be completely substituted to act as strong bases.

the resonance stabilization of the benzene ring allows it to act as an electron-withdrawing group, inhibiting the basicity of the amine.

the benzene ring hydrogen bonds with the amine, hindering its ability to act as a base.
