JEE Main Chemistry question

contains a basic group, but does not, essentially because

(A)Acetamide is amphoteric in character
(B)In , the electron pair on the N-atom is delocalised by resonance
(C)In there is no resonance, while in acetamide the lone pair on the N-atom is delocalised and therefore less available for protonationCorrect
(D)None of the above

Answer: (C)

Solution

In ethylamine, the nitrogen lone pair is fully localised on nitrogen and freely available to accept a proton, giving normal amine basicity. In acetamide, by contrast, the nitrogen lone pair is conjugated with the
