JEE Main Chemistry question

Statement 1: R–C≡O⁺ is more stable than R–C⁺=O. Statement 2: Resonance in the carbonyl compound provides C⁺ and O⁻.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Statement 1 is true: the acylium-type cation with a full C≡O triple bond and formal positive charge on the terminal, electronegative oxygen is a poor resonance structure, whereas a resonance structure bearing the positive charge on carbon with the full double bond to oxygen retained in a different sense is actually
