Question

hydrogen is passed through vegetable oil in presence of catalist nickel.Name the process and write chemical equation,Write on difference between the physical properties of reactant and product on this

Answer 1

hydrogenation reaction
alkene + H2 gives alkane

Answer 2

Explanation:

Hydrogen is passed through vegetable oil in nickel presence as catalyst is called Hydrogenation.

The chemical reaction of hydrogenation is as follows:

In the hydrogenation reaction, ethene is a reactant and ethane is a product.

Ethene is an alkene because it has double bond.

Physical properties of alkenes:

• Soluble in polar solvents and insoluble in water.
• It has low boiling and melting points.
• Ethane is an alkane because it has single bond.

Physical properties of alkanes:

• Alkanes are soluble in nonpolar solvents.
• It has high melting point and high boiling points.
