Acetaldehyde undergoes polymerization with concentrated H2SO4 to form _.
Correct answer: B. Paraldehyde
- A. Acetylides
- B. Paraldehyde
- C. Bakelite
- D. Meta Acetaldehyde
Explanation

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.
