CH3MgBr reacts with CH2O to give:
Correct answer: A. 10 Alcohol
- A. 10 Alcohol
- B. 20 Alcohol
- C. 30 Alcohol
- D. Carboxylic acid
Explanation
When CH3MgBr, which is methylmagnesium bromide, reacts with CH2O, which is formaldehyde, it undergoes a nucleophilic addition reaction. In this reaction, the methyl group from CH3MgBr adds to the carbon atom of the carbonyl group in CH2O, resulting in the formation of a primary alcohol. The primary alcohol has the hydroxyl group (-OH) attached to a carbon atom that is bonded to only one other carbon atom.

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.
