Question

The reaction in which C2H4 is converted into C2H6, in the presence of a catalyst is called –
a) Oxidation
c) Substitution
b) Addition
d) Dehydration​

Answer 1

The reaction in which $C_{2}H_{4}$ is converted into $C_{2}H_{6}$, in the presence of a catalyst is called Addition

Explanation:

• The process by which double or triple bond hydrocarbons like $C_{2}H_{4}$ (ethene) is converted into single bonded hydrocarbons like $C_{2}H_{6}$ ( ethane) in the presence of catalysts is called as catalytic hydrogenation or addition reaction of hydrogen.
• In this process, the catalysts used are generally nickel, palladium, or platinum.
• In the process, the double or triple bonds between carbon atom is broken and single bonds are formed.
• Since it is completed by the addition of hydrogen it is also called as Addition of Hydrogen.
