Ozonolysis of an alkene produces only one dicarbonyl compound. The structure of the alkene is

• A

  $\mathrm{H}_{3} \mathrm{C}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_{3}$
• Correct answer
  B

  
• C

  
• D

  $\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_{2}$

Solution

Only gives one compound on ozonolysis. All other options give more than one aldehyde/ketone on ozonolysis.

Hence, the correct answer is option: 'B'.
