Which of the following is one of the product of ozonolysis at ozone layer in atmosphere?
Options
- Aalcohol
- Bacid
- Caldehyde
- Dester
Correct answer
C. aldehyde
Step-by-step solution
Ozone ( O₃ ) in the atmosphere undergoes ozonolysis with unsaturated hydrocarbons, cleaving carbon-carbon double bonds to form carbonyl compounds. The reaction proceeds through an unstable ozonide intermediate that decomposes to aldehydes or ketones depending on substituents. The general ozonolysis reaction is: R₁R₂C=CR₃R₄ + O₃ R₁R₂C=O + R₃R₄C=O When R is hydrogen, aldehydes form; with alkyl groups, ketones result. Among the options, aldehydes are direct products of ozonolysis, while alcohols, acids, and esters are
