Given below are two statements.
Statement I: In base-catalysed aldol reactions, the key step is enolate formation; therefore the acidity of 
-hydrogens of aldehydes/ketones is responsible for the reaction.
Statement II: A mixture of benzaldehyde and ethanal under base does not produce any cross-aldol product.
In the light of the above statements, choose the most appropriate answer from the options given below:
Text Solution
Verified by ExpertsA
Base-catalysed aldol proceeds via enolate formation from 
-hydrogens (true). Benzaldehyde lacks 
, so with ethanal (which has 
) a crossaldol does form (ethanal enolate adds to benzaldehyde) - hence Statement II is false.
