Assertion: The double bond of carbonyl group
has higher bond energy than double bond in
alkenes.
Reason: Carbonyl group has hybridisation.
has higher bond energy than double bond in
alkenes.
Reason: Carbonyl group has hybridisation.
View answer and explanation
Correct option: B
If both Assertion and Reason are correct, but
Reason is not the correct explanation of
Assertion
Reason is not the correct explanation of
Assertion
Option B is correct because the assertion that the double bond of a carbonyl group has higher bond energy than the double bond in alkenes is true, but the reason (sp² hybridization) doesn't explain it. The higher bond energy is due to the polarity of the C=O bond.
