Which of the compounds with molecular formula C ₅ H ₁₀ yields acetone on ozonolysis?

Options

  1. A3-Methyl-l-butene
  2. BCyclopentane
  3. C2-Methyl-1-butene
  4. D2-Methyl-2-butene

Correct answer

D. 2-Methyl-2-butene

Step-by-step solution

2-methyl-2-butene (molecular formula ( C ₅ 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
