Concepts and reason

Epoxides (cyclic ethers) are reactive towards nucleophile due to the ring strain present in the structure. They undergo chemical reactions with both acids and bases. Both chemical reactions result in the formation of an alcohol.

Fundamentals

Grignard reagent is a strong nucleophile, it attacks on the less substituted side of the epoxide ring and generates an anion which on treatment with aqueous acidic solution gives corresponding alcohol.

Nucleophilic attack of ethyl anion on the less substituted carbon of epoxide ring.
