Take CBT

Question

Which reagent converts an alkene to an aldehyde with one fewer carbon (oxidative cleavage)?
Options
A O₃ followed by Zn/H₂O
Correct Answer
B Cold KMnO₄
C OsO₄
D BH₃ then H₂O₂/OH⁻
Correct Answer

Option A is the correct answer.

Detailed Explanation

Ozonolysis with reductive workup cleaves the double bond to carbonyl compounds; a terminal =CH₂ gives formaldehyde (escapes), effectively reducing carbon count.

Hint

Cleavage with reductive workup.
