Acid hydrolysis of acetaldehyde in the presence of Grignard Reagent produces:
Correct answer: B. Secondary alcohol
- A. Ketone
- B. Secondary alcohol
- C. Aldehyde
- D. Ketone and alcohol
Explanation
The addition of Grignard reagent (RMgX) to acetaldehyde will hydrolyze it to give secondary alcohol. Basically, these organometallic compounds react with C=O bonds of aldehyde and break it to produce alcohol. The reaction of RMgX with formaldehyde yields primary alcohol while that with a ketone yields tertiary alcohol.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
