Ethylene oxide when treated with Grignard reagent yields

1. Tertiary alcohol
2. Cyclopropyl alcohol
3. Primary alcohol
4. Secondary alcohol

Correct answer: Primary alcohol

Solution

Ethylene oxide reacts with a Grignard reagent to form a primary alcohol after hydrolysis. The reaction involves nucleophilic attack by the Grignard reagent on the epoxide ring, followed by protonation.
