Question

Which molecule possibly shows Aldol
condensation reaction​

Answer 1

Ethyl 2-methylacetoacetate and campholenic aldehyde react in an Aldol condensation. The synthetic procedure is typical for this type of reaction. In the process, in addition to water, an equivalent of ethanol and carbon dioxide are lost in decarboxylation.

Answer 2

Aldehydes and ketones having at least one α-hydrogen undergo aldol condensation.

• Aldehydes and ketones with alpha hydrogen exhibit aldol reactions.
• The carbon atom close to the carbonyl carbon of an aldehyde or ketone is referred to as alpha carbon, and the hydrogen linked to alpha carbon is referred to as alpha hydrogen.
• The methyl group in the acetaldehyde mentioned above is an alpha group.
• Because it contains alpha hydrogen, it can undergo aldol condensation.
• Aldol condensation occurs when an enol or an enolate ion combines with a carbonyl chemical to generate a -hydroxy aldehyde, hydroxy aldehyde, or -hydroxy ketone, which is then dehydrated to form a conjugated enone.
