Expert Solution
Step 1: Introduction to the reagents


LiAlH4 is a very strong reducing agent, used to reduce almost all carbonyl derivatives. With ester it reacts to give corresponding alcohol, One equivalent of LiAlH4 can reduce two equivalents of ester. Aprotic solvents are required to carry out these reactions.
