Question

Ethylene oxide when treated with Grignard reagent yields: alcohol

• A. Primary alcohol
• B. Secondary alcohol
• C. Tertiary alcohol
• D. Cyclopropyl alcohol

Answer 1

The correct option is A

Primary alcohol

Explanation:

• Ethylene oxide on treatment with Grignard reagent forms primary alcohol.

Step1: Reaction of ethylene oxide with Grignard reagent

Ethylene oxide on treatment with Grignard reagent undergoes an addition reaction.

Step 2: Hydrolysis

The additive product formed in step 1 undergoes hydrolysis to form primary alcohol.

Thus, Ethylene oxide on treatment with Grignard reagent forms primary alcohol.

Hence, option (A) is correct.
