Which of the following products is formed when alcohol is added to acetaldehyde?
Correct answer: A. Acetal
- A. Acetal
- B. Ketal
- C. Carboxylic acid
- D. Alcohol
Explanation
Option A is correct since when alcohol is added to aldehyde, an acetal is formed.Option B is incorrect since ketal is formed when ketone is added to alcohol.Option C is incorrect since carboxylic acid is not formed when alcohol is added to the aldehyde.Option D is incorrect since alcohol is formed when acetal is hydrolyzed using an acid.

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.
