Statement 1: Esters which contain $\mathrm{\alpha }$-hydrogens undergo Claisen condensation.

Statement 2: LiAlH₄ reduction of esters gives acids.

It is known that esters with $\alpha$-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 p-keto ester. LiAlH₄ reduces esters to alcohols.
