Oxidation of secondary alcohols:
When a secondary alcohol undergoes oxidation, it is converted into a ketone. The process involves the loss of two hydrogen atoms and the formation of a double bond between the carbon and oxygen atoms.
Reaction mechanism:
1. The secondary alcohol is first oxidized to a ketone by a strong oxidizing agent such as potassium dichromate (K2Cr2O7) or potassium permanganate (KMnO4).
2. In the presence of an acid catalyst, the alcohol reacts with the oxidizing agent to form a chromate ester intermediate.
3. The chromate ester then undergoes a rearrangement, resulting in the formation of a ketone.
Example:
Let's consider the oxidation of a secondary alcohol, 2-propanol (CH3-CH(OH)-CH3), to form acetone (CH3-CO-CH3).
1. The secondary alcohol is reacted with an oxidizing agent, such as potassium dichromate and sulfuric acid (H2SO4).
2. The alcohol is oxidized to form a chromate ester intermediate, 2-propyl chromate (CH3-CH(CrO3)-CH3).
3. The chromate ester undergoes a rearrangement, resulting in the formation of acetone.
Overall reaction:
2-propanol + [O] → acetone + H2O
Therefore, the oxidation of secondary alcohols is a reliable method for the synthesis of ketones. It is an important reaction in organic chemistry and is widely used in the laboratory and industrial settings.

In oxidation when we add oxygen it removes 2 hydrogens from the secondary carbon and O in OH forms double with carbon.ketone is formed.Option A gives carboxlic acid.option B gives aldehyde.option C gives alkene
