Which of the following alcohols cannot be synthesized when Grignard reagent reacts with aldehydes and ketones?
Correct answer: D. Methanol
- A. Ethanol
- B. Isobutyl alcohol
- C. Propanol
- D. Methanol
Explanation
Methanol cannot be synthesized directly from the reaction of a Grignard reagent with an aldehyde or ketone. This is because there is no way to add a methyl group (CH3-) to the carbonyl carbon using a Grignard reagent.

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.
