Ethylene epoxide treated with Grignards reagent followed by acid hydrolysis yield __________________?
Correct answer: A. primary alcohol
- A. primary alcohol
- B. secondary alcohol
- C. tertiary alcohol
- D. dihydric alcohol
Explanation
A Grignard reagent opens ethylene oxide and adds its organic group to the ring; acid hydrolysis then converts the magnesium alkoxide into a terminal -OH group. The product is therefore a primary alcohol. Students may choose a different alcohol class by focusing on the Grignard reagent rather than the less substituted epoxide opening.

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
