Q. A mixture of cinnamaldehyde and crotonaldehyde is treated with concentrated alkali,

Which statement is not true about the above reaction?

Aldehydes Ketones and Carboxylic Acids Report Error

Aldol condensation takes place and $\alpha$-carbon atom of crotonaldehyde provides the carbanion.

Aldol condensation takes place and $\gamma$-carbon atom of crotonaldehyde provides the carbanion.

Aldol condensation takes place and $\beta$-carbon atom of crotonaldehyde provides the carbanion.

Aldol condensation takes place and product will be saturated carbonyl compound.

Solution:

Removal of $\gamma$-hydrogen of crotonaldehyde provides more stable allylic carbanion, hence here $\gamma$-carbon (not $\alpha$ ) provides the carbanion (nucleophile) for carbonyl carbon of cinnamaldehyde.
