Question

Which of the following compounds will give butanone on oxidation with alkaline $KMn{O}_4$ solution?

• A. None of these
• B. Butan $-2-ol$
• C. Butan $-1-ol$
• D. Both of these

Answer 1

The correct option is B Butan $-2-ol$

Oxidation using alkaline $KMn{O}_4$

Alkaline $KMn{O}_4$ is a strong oxidising agent that coverts primary alcohols to carboxylic acid and secondary alcohols to ketones.

Analysing the options

Option (A)

When alkaline $KMn{O}_4$ reacts with primary alcohol, it oxidises the primary alcohol to a carboxylic acid.


Option (B)

When alkaline $KMn{O}_4$ react with secondary alcohol, it oxidises the secondary alcohol to a ketone.



Hence, option B is the correct answer.
