Assertion : Esters which contain $\alpha$-hydrogens undergo Claisen condensation.
Reason : $\mathrm{LiAlH}_4$ reduction of esters gives acids.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false.
Solution
It is known that esters with $\alpha$-hydrogens form carbanion when treated with base. It brings about nucleophilic substitution at the carbonyl group of the other molecule of the ester to yield $\beta$-keto ester. $\mathrm{LiAlH}_4$ reduces esters to alcohols.
