प्रश्न
Which of the following compounds will not exist as resonance hybrid. Give reason for your answer:
विकल्प
CH3OH
R – CONH2
CH3CH = CHCH2NH2
उत्तर
CH3OH
Explanation:
(i) CH3OH does not contain -electrons, hence, it cannot exist as resonance hybrid.
(ii) Due to the presence of -electrons in C = O bond and lone pair of electrons on N, amide can be represented by the following resonating structures.
(iii) CH3CH = CHCH2NH2: Since lone pair of electrons on nitrogen atom is not conjugated with the -electrons, therefore, resonance is not possible.
