Which of the compounds with molecular formula $\mathrm{C}_5 \mathrm{H}_{10}$ yields acetone on ozonolysis?
  1. 3-Methyl-l-butene
  2. Cyclopentane
  3. 2-Methyl-1-butene
  4. 2-Methyl-2-butene

Solution

2-methyl-2-butene (molecular formula \(\mathrm{C}_5 \mathrm{H}_{10}\)) yields acetone on ozonolysis.
Related Theory Ozone is a very reactive allotrope of oxygen. The reaction of ozone with alkenes and alkynes causes the oxidative cleaving of the alkene or alkyne. The carbon-carbon triple bonds are replaced with carbon-oxygen double bonds, giving the required carbonyl product
