An unknown alkene on ozonolysis with O ₃ followed by treatment with H ₂ O ₂ yields propan-2-one and butanoic acid as the only organic products. The IUPAC name of the starting alkene is:

Options

  1. A2-methylhex-3-ene
  2. B3-methylhex-2-ene
  3. C2-methylhex-2-ene
  4. D2,3-dimethylpent-2-ene

Correct answer

C. 2-methylhex-2-ene

Step-by-step solution

The reaction conditions ( O ₃ followed by H ₂ O ₂ ) correspond to oxidative ozonolysis. Under these conditions, a disubstituted alkene carbon yields a ketone, while a monosubstituted alkene carbon yields a carboxylic acid. The products are propan-2-one (a ketone) and butanoic acid (a carboxylic acid). Propan-2-one is CH ₃- C (= O )- CH ₃ , which indicates that one side of the original double bond was a disubstituted carbon with two methyl groups: ( CH ₃)₂ C = . Butanoic acid is CH ₃ CH ₂ CH ₂ COOH . In oxidative oz
