Q. 45

Which of the following compounds will not exist as resonance hybrid. Give reason for your answer:

(i) CH3OH

(ii) R—CONH2

(iii) CH3CH = CHCH2NH2

Answer :

CH3OH will not exist as resonance hybrid, because CH3OH do not have any conjugation possible (as we know that the conjugation is possible only when any atom having loan pair or positive charge or negative charge is present at the alternate position of the double bond).

As there is an Oxygen atom having loan pairs of electron, but no double bond is present for conjugation.


Whereas in R—CONH2, has conjugation in between the C=O bond and the loan pair of electrons present at the N atom in –NH2 group.


And in CH3CH = CHCH2NH, there is also conjugation in between the C=C bond and the loan pair of electrons present at the N atom in –NH2 group.
