Q. Which of the compounds with molecular formula C₅H₁₀ yields acetone on ozonolysis?
A) 3-methyl-1-butene
B) cyclopentane
C) 2-methyl-1-butene
D) 2-methyl-2-butene
Explanation
[Solution from source] Acetone needs a (CH₃)₂C= unit. 2-Methyl-2-butene (CH₃)₂C=CHCH₃ gives acetone + acetaldehyde on ozonolysis. 2-Methyl-1-butene gives butanone + formaldehyde, and cyclopentane has no double bond. Answer (4).
