    The vegetable oils (like groundnut oil, cotton seed oil and mustard oil) are unsaturated compounds containing double bonds. They are in the liquid state at room temperature. Due to the presence of double bonds, vegetable oils undergo addition of hydrogen just like alkenes to form saturated products called vegetable ghee or vanaspati ghee which are solid (or semi-solid) at the room temperature.

    An example of the hydrogenation of oils is given below:  Vegetable oils are unsaturated fats having double bonds between some of their carbon atoms. When a vegetable oil (like groundnut oil) is heated with hydrogen in the presence of finely divided nickel as catalyst, then a saturated fat called vegetable ghee (or vanaspati ghee) is formed.
