Paraldehyde is polymer of:
Correct answer: B. CH3CHO
- A. HCHO
- B. CH3CHO
- C. CH3COCH3
- D. CH3CH2CH2OH
Explanation
Paraldehyde is polymer of acetaldehydeUses of Acetaldehyde1. It is used in the production of acetic acid, acetic anhydride, n-butanol, ethanol,2-ethyl-1-hexanol, vinyl acetate, paraldehyde, ethylacetate, etc.2. It is used to make acetaldehyde ammonia used as a rubber-accelerator.3. It is used to make chloral hydrate, ethanol trimer and tetramer. Chloral hydrateand ethanol trimer are both used as hypnotic drugs whereas ethanol tetramer isused as a slug poison.4. It is used as an antiseptic inhalent in nasal infections.5. It is used in silvering of mirrors.6. It is used to make phenolic resins and synthetic drugs.

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.
