Which of the following compounds will not exist as resonance hybrid. Give reason for your answer.
1.
2.
3.
(a) As it lacks -electrons hence it will not exist as resonance hybrid.
(b) Due to the presence of n-electrons on N and -electrons on C=O bond, hence amide can be represented as a resonance hybrid of the following three resonating structures.
(c) As the lone pair of electrons on the N-atom is not conjugated with the -electrons of the double bond, thus, resonance is not possible and hence no resonance hybrid will exist.
