If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

Vedclass · Answer

(B) The Assertion is correct because protonation of the carbonyl oxygen atom increases the positive charge on the carbon atom,thereby enhancing its electrophilic character. The Reason is also correct because the oxygen atom of the carbonyl group acts as a nucleophile (due to lone pairs) and accepts a proton $(H^+)$,which is an electrophile. However,the Reason is not the correct explanation for the Assertion,as the increased electrophilicity is a consequence of the resonance effect and inductive effect induced by the positive charge on oxygen,not simply the fact that an electrophile was added.

Assertion : Protonation of a carbonyl group increases its electrophilic character.
Reason : Protonation of a carbonyl group involves addition of an electrophile on nucleophilic oxygen.
