Question

Ethanal undergoes aldol condensation give reason

Answer 1

Only Compounds having alpha hydrogen undergoes aldol condensation and ethanal has alpha hydrogen that is why it undergoes aldol condensation Hope this helps you

Ethanal (CH3CHO) ( C H 3 C H O ) undergoes aldol condensation reaction due to presence of α− hydrogen atom. Aldol condensation reaction is given by aldehydes and ketones having α− hydrogen atom. Aldehydes and ketones lacking α− hydrogen atom undergo Cannizzaro reaction.
