When an oxidizer, such as hydrogen peroxide (H2O2) or potassium permanganate (KMnO4), is mixed with a ketone, the ketone undergoes oxidation. Ketones are organic compounds that contain a carbonyl group (C=O) bonded to two alkyl or aryl groups.

In the oxidation reaction, the ketone is converted into a carboxylic acid. The carbonyl group of the ketone is oxidized to a carboxyl group (-COOH), and the two alkyl or aryl groups become attached to the carboxyl group.

The specific products of the oxidation reaction depend on the ketone and the oxidizer used. For example, when acetone (CH3COCH3) is oxidized with hydrogen peroxide, the product is acetic acid (CH3COOH).

The oxidation of ketones is a common reaction in organic chemistry. It is used to synthesize carboxylic acids, which are important intermediates in the synthesis of a wide variety of organic compounds.

Here is the general reaction scheme for the oxidation of a ketone with hydrogen peroxide:

R2C=O + H2O2 → R2C(O)OH + H2O

where R represents an alkyl or aryl group.
