Acetamide is a much weaker base than ammonia. This is because
(a) the electron withdrawing effect of the C=O group makes the lone pair of
electrons on nitrogen atom less available for protonation.
(b) ) the electron withdrawing effect of the C=O group makes the lone pair of
electrons on nitrogen atom more available for protonation.
(c) the presence of CH3 group sterically hinders the protonation of the NH2 group.
(d) an H atom from the nitrogen is less easily lost from CH3CONH2 than from
NH3.
