Question

Out of the following compounds, how many compounds will be oxidised to carboxylic acid by Jones reagent ( H 2 ​ CrO 4 ​ + aqueous acetone)

TestHub · Accepted Answer

Question Explanation:

Count how many of the given compounds are oxidised to carboxylic acids by Jones reagent.

Concept:

This question is based on oxidation reaction of different functional group by Jones reagent (H₂CrO₄ + aq. acetone).

Solution:

Jones reagent oxidises primary alcohols (including benzylic alcohols) to carboxylic acids.

Secondary alcohol → ketones

Tertiary alcohol → no oxidation

Applying these rules, compounds II, VI, VII, and VIII are oxidised to carboxylic acids by Jones reagent.

Final answer: 4
