Hydration of hydrocarbon give carbonyl compound, the general formula of that hydrocarbon is:

Correct answer: C. CnH2n-2

  • A. CnH2n+2
  • B. CnH2n
  • C. CnH2n-2
  • D. Both CnH2n and CnH2n-2

Explanation

Alkynes on hydration in the presence of H2SO4 and HgSO4 yield carbonyl compounds through enolAll alkynes except ethyne give ketones while ethyne gives aldehyde.

About Alkynes

Alkynes are unsaturated hydrocarbons containing a carbon-carbon triple bond, with sp-hybridised carbon atoms and a linear arrangement around the bond. The content includes nomenclature, preparation, acidity of terminal alkynes, and addition reactions with hydrogen, halogens, hydrogen halides and water, as well as oxidation.
