Question

Aldol condensation is:

• A. self-condensation of aldehydes only having at least one alpha hydrogen
• B. self-condensation of ketones only having at least one alpha hydrogen
• C. self-condensation of both aldehydes and ketones having at least one alpha hydrogen
• D. self-condensation of both aldehydes and ketones having no alpha hydrogen

Answer 1

The correct option is C self-condensation of both aldehydes and ketones having at least one alpha hydrogen

Aldol Condensation, in organic chemistry, is a condensation reaction of enol aka enolate and carbonyl compound. When enol ions react with carbonyl compound it forms a $\beta -$hydroxy ketone or $\beta -$hydroxy aldehyde. This process is followed by dehydration which results in conjugated enone. And Alpha-hydrogen atom is an atom in which the hydrogen atom is reacted with the alpha-carbon atom. Similarly, the beta-hydrogen atom is an atom in which the hydrogen atom is reacted with the beta-carbon atom.

Self-condensation is an organic reaction in which a chemical compound containing a carbonyl group acts both as the electrophile and the nucleophile in an aldol condensation.

A condensation reaction in which two of the same molecule are condensed. This aldol condensation is a self-condensation reaction because two molecules of acetone combine to form the product.
