Would you expect benzaldehyde to be more reactive or less reactive nucleophilic addition?

Polarity of carbonyl group is in benzaldehyde reduced due to resonance making it less reactive in nucleophilic addition reactions. There is no such resonance effect in propanal and so the polarity of carboxyl group in it is more than in benzaldehyde. This makes propanal more reactive than benzaldehyde.

Is benzaldehyde more reactive towards nucleophilic?

Benzaldehyde is more reactive than ethanol towards nucleophilic attack.

Would you expect P nitro benzaldehyde to be more reactive or less reactive in nucleophilic addition reaction than benzaldehyde explain your answer?

In p-nitrobenzaldehyde, the NO2 group is a powerful electron-withdrawing group. It withdraws electrons both by inductive and resonance effect thereby decreasing the electron density on the carbon atom of carboxyl group. This facilitates the attack of the nucleophile and hence makes it more reactive than benzaldehyde.

Which of the following is more reactive than benzaldehyde towards nucleophilic addition?

Formaldehyde
Statement-1: Formaldehyde is more reactive than benzaldehyde for nucleophilic addition reaction.

Would you expect benzaldehyde to be more or less reactive?

The carbon atom of the carbonyl group of benzaldehyde is less electrophilic than carbon atom of the carbonyl group present in propanal. The polarity of the carbonylgroup is reduced in benzaldehyde due to resonance as shown below and hence it is less reactive than propanal.

Why is benzaldehyde less reactive in nucleophilic addition reaction than propanol?

As a result, the carbon atom of the carbonyl group of benzaldehyde is less electrophilic than carbon atom of the carbonyl group in propanal and hence benzaldehyde is less reactive than propanal in nucleophilic addition reactions.

Why is benzaldehyde less reactive in nucleophilic addition reaction?

C-atom of Carbonyl group of benzaldehyde is less electrophilic than C-atom of Carbonyl group in acetaldehyde. Polarity of Carbonyl group is in bonzaldehyde reduced due to resonance making it less reactive in nucleophillic addition reactions.

Which is more reactive towards nucleophilic addition reaction benzaldehyde or acetaldehyde?

A : Benzaldehyde is more reactive towards nucleophilic addition than acetaldehyde. R : Benzaldehyde has less steric hindrance than acetaldehyde.

Would you expect benzaldehyde more reactive or less?

Why aldehydes are more reactive than benzaldehyde?

Acetaldehyde is more reactive than benzaldehyde. This is because the carbon of the carbonyl group in the benzaldehyde is less electrophilic than the carbon of the carbonyl group in the acetaldehyde.

Why benzaldehyde is least reactive towards nucleophilic addition reaction?

Is benzaldehyde more or less reactive than propanal?

Benzaldehyde is less reactive than propanal. This can also be interpreted as Benzaldehyde is more stable than propanal. All compounds that have an aromatic character are always more stable than the groups having aliphatic character. This is because resonance always stabilises a molecule.
