What do we get after oxidation of alcohols?

The process of the addition of oxygen to a substance in a chemical reaction is called oxidation. This is done with the help of an oxidizing agent which actually facilitates oxygen.

Examples of oxidizing agents are KMnO₄, K₂Cr₂O_7, etc. When an oxidizing agent adds oxygen to the alcohol compound, the alcohol gets converted into carboxylic acids. The reaction occurs in the following way:
RCH₂OH + KMnO₄ $\to$ RCOOH, where R - can be any alkyl group.
