Question

What happens when hydrogen is added to the physical property of the vegetable oil and the product obtained in its reaction . Write the role of nickel in its reaction

Answer 1

during hydrogeneration vegetables oil are hardened by reacting them with hydrogen gas at about 60 degree Celsius Nickel catalyst is used to speed up the reaction the double bonds are converted to single bonds by hydrogenization in this way unsaturated fats can be made into saturated fats

Answer 2

when hydrogen is added to vegetable oil then it gets converted into vanaspati ghee.The reaction in which hydrogen is added in an unsaturated compound to convert it into saturated compound in presence of any catalyst such as nickel or palladium is known as addition reaction.
nickel in this reaction is used as catalyst which speeds up the rate of reaction.
so the reaction of converting unsaturated vegetable oil into saturated vanaspati ghee greatly speeds up when nickel catalyst is used.
