Assertion: Benzaldehyde is more reactive...

Assertion: Benzaldehyde is more reactive than ethanal towards nucleophilic attact.
Reason : The overall effect of- `l` and `+R` effect of phenyl group decrease the electron density on the carbon atom of `gtC = O` group in benzaldehyde.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D

Benzaldehyde is less reactive than ethanol towards nucleophilic attack. The combined effect of –I and +R effect of phenyl group is electron donating which increases the electron density on the carbon atom of the `gt` C = O in benzaldehyde.
