Question

Statement-1 : Benzaldehyde is more reactive than ethanol
towards nucleophilic attack.
Statement-2 : The overall effect of –I and + R effect of phenyl
group decreases the electron density on the carbon atom of
> C = O group in benzaldehyde.

Answer 1

Explanation:

Benzaldehyde is more reactive than ethanol towards nucleophilic attack.

The overall effect of -I−I and +R+R effect of phenyl group decreases the electron density on the carbon atom of >C = O>C=O group in benzaldehydes.

Answer 2

Both the statements are correct and statement 2 correctly describes statement 1.

Explanation:

• Benzaldehyde is an aryl aldehyde whereas ethanal is an aliphatic aldehyde.

• The Benzaldehyde has the attraction towards nucleophilic substitution which is also seen in case of ethanal.

• But in the benzaldehyde, there is negative inductive effect which draws electron from the carbonyl carbon.

• It also has +R effect that can very well stabilize the carboncation.

• Whereas in ethanal, there is +I effect and no resonance stability of the charge.

• So the electron density is higher in ethanal than in Benzaldehyde.

• So benzaldehyde will be more prone to nucleophilic attack.
