Chemistry - Hydrocarbon Question with Solution | TestHub

Alkenes undergo oxidative cleavage when treated with a strong oxidizing agent like ${\text{KMnO}}_4$ in acidic medium (dilute ${\text{H}}_2{\text{SO}}_4$).

During this reaction, the carbon-carbon double bond is completely cleaved. A $=\text{CH}-$ group is initially oxidized to an aldehyde (alkanal), which is highly susceptible to further oxidation under these conditions and immediately oxidizes to a carboxylic acid (alkanoic acid).

For example:
$\text{R}-\text{CH}=\text{CH}-{\text{R}}^{\prime }\stackrel{{\text{KMnO}}_4/{\text{H}}^{+}}{\to }\text{R}-\text{COOH}+{\text{R}}^{\prime }-\text{COOH}$

Thus, the final stable product formed is an alkanoic acid.

Answer: Alkanoic acid
