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

Solution:

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