Why tertiary alcohol does not undergo reaction during oxidation ?

Tertiary alcohols do not undergo oxidation reactions because they lack a hydrogen atom attached to the carbon atom bearing the hydroxyl group. In oxidation reactions, the hydroxyl group is converted into a carbonyl group (C=O) by the removal of a hydrogen atom and the addition of an oxygen atom. However, tertiary alcohols do not have a hydrogen atom on the carbon atom adjacent to the hydroxyl group, so there is no hydrogen atom available for removal and subsequent oxidation. As a result, tertiary alcohols are resistant to oxidation reactions.
