Question

Consider the above reaction, the product 'X' and 'Y' respectively are 

• A. A
• B. B
• C. C
• D. D

Hint:

Aldol products always follow this sequence: Aldol (Addition) $\xrightarrow{-H_2O}$ Enone (Condensation). The double bond in the final product is always between $\alpha$ and $\beta$ carbons.

Answer 1

The Correct Option is A

Step 1: This is an Aldol Condensation of cyclopentanone.
Step 2: In the presence of dil. \(NaOH\), one molecule of cyclopentanone forms an enolate and attacks another molecule to form the \(\beta\)-hydroxy ketone (Product 'X').
Step 3: Upon heating (often in acidic medium for final dehydration), a molecule of water is lost to form the \(\alpha,\beta\)-unsaturated ketone (Product 'Y').
