Position of double bond in an organic compound is determined by ___________?

Correct answer: A. Ozonolysis

  • A. Ozonolysis
  • B. Oxidation
  • C. Reduction
  • D. Hydrogenation

Explanation

Ozonolysis breaks a carbon-carbon double bond and produces carbonyl compounds whose structures reveal which groups were attached to the original double-bonded carbons. By identifying these products, the original position of the double bond can be determined. The likely mistake is choosing hydrogenation because it reacts at the double bond, but it removes the unsaturation without giving structural fragments that locate it.

About Alkenes

Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
