During the hydrolysis of an acetal in an acidic environment, the acetal is converted back into
Correct answer: B. Option B: Aldehyde
- A. Option A: Ethanol
- B. Option B: Aldehyde
- C. Option C: Ketone
- D. Option D: Carboxylic Acid
Explanation
The correct answer is Option B: Aldehyde. Acetals are derivatives of aldehydes or ketones formed by the reaction of two alcohol molecules with a carbonyl group. When acetals undergo hydrolysis in the presence of an acid, they revert to the original aldehyde and release alcohol. The other options are incorrect because they either involve incorrect functional groups (ethanol, ketone) or result in a product not formed in this reaction type (carboxylic 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.
