It is known that esters with a-hydrogens form carbanion when treated with base. It bring about nucleophilic substitution at the carbonyl group of the other molecules of the ester to yield (β-keto ester. LiAlH4 reduces esters to alcohols.

Q. Statement 1: Esters which contain $α$ -hydrogens undergo Claisen condensation.
Statement 2: $L i A l H_{4}$ reduction of esters gives acids.
