CHM 102 Alkenes: Structure, Bonding, and Geometrical Isomerism Objective Question

Question

Which of the following reactions cleaves the double bond of an alkene to produce carboxylic acids or ketones?
Options
A Hydroboration-oxidation
B Ozonolysis or hot KMnO4
Correct Answer
C Hydration
D Halogenation
Correct Answer

Option B is the correct answer.

Detailed Explanation

Vigorous oxidation with hot KMnO4 or ozone (ozonolysis) cleaves the double bond; terminal =CH2 gives CO2, =CHR gives carboxylic acid, and =CR2 gives ketone.

Hint

Cleavage = breaking the double bond completely.
