1.	How r vegetable oils converted into vegetable ghee???Name and define the process involved??
Answer» The vegetable oils are unsaturated compounds containing double bonds. They are in 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. It is an example of the hydrogenation of oils. When a vegetable oil is heated with hydrogen in the presence of finely divided nickel as catalyst, then a saturated fat called vegetable ghee is formed.
