Explanation:
CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS
323651

CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS
323652
Assertion : Esters which contain \(\alpha\)-hydrogens undergo Claisen condensation. Reason : \(\mathrm{LiAlH}_{4}\) reduction of esters gives acids.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Esters with \(\alpha\)-hydrogens exhibit versatility, undergoing nucleophilic substitution to form keto esters and reduction to form alcohols using \(\mathrm{LiAlH}_{4}\). So the option (3) is correct.

In the reaction, The major product formed is
The given reaction is an example of Perkin condensation. In this reaction, aromatic aldehydes react with acid anhydride of an aliphatic acid in presence of sodium salt of same acid to form \(\alpha, \beta\)-unsaturated acid. The steps involved in the process are as follows : Thus, the correct option is (3).
