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.

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.
