Compare the reactivity of benzaldehyde and ethanal towards nucleophilic addition reactions. Write the cross aldol condensation product between benzaldehyde and ethanal.
Answers
Answer:
The carbon atom of the carbonyl group of benzaldehyde is less electrophilic than carbon atom of the carbonyl group present in ethanal. The polarity of the carbonyl group is reduced in benzaldehyde due to resonance hence less reactive than ethanal.

The reactivity of benzaldehyde and ethanal towards nucleophilic addition reactions : Bezaldehyde is less reactive than ethanal .
Explanation:
Nucleophilic addition
The nucleophilic addition reaction is an addition reaction in which a chemical compound having double or triple bond, reacts with electron-rich reactant, termed a nucleophile and as a result single bond in place of double is formed .
