Cyclohexanol is a secondary alcohol, formula C6H11OH, consisting of a cyclohexane ring with one hydrogen substituent replaced by a hydroxyl group.
It can be oxidized to cyclohexanone (ketone) by Chromic acid (by dissolving Sodium dichromate in water and concentrated sulphuric acid). The oxidation will stop at cyclohexanone, as a stronger oxidizing agent is required to break the carbon bond.
