Question

What happen when hydrogen is added to a vegetable oil in the presence of nickle? Name the reaction and write one difference between the physical property of the vegetable oil and the product obtained in this reaction. Write the role of nickle in this reaction

Answer 1

Hydrogenation – meaning, to treat with hydrogen – is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons.

Hope this helps you

Answer 2

It will form dalda ghee/vanaspati/vegetable ghee. The reaction is a reduction reaction. In this Ni acts as a catalyst.
