Question

The reaction of Acetylene and hydrogen in the presence of heated nickel powder is called
A. Substitution reaction
B. Addition reaction
C. Dissociation reaction
D. Decomposition reaction​

Answer 1

Answer:

The reaction of acetylene and hydrogen in the presence of heat nickel powder is called ethene reaction.

Answer 2

Answer:

The reaction of Acetylene and hydrogen in the presence of heated nickel powder is called the Addition reaction

Explanation:

However, only chemical compounds with multiple bond properties can undergo an addition reaction, as one double or triple bond is usually cleaved to form the required single bond. Addition reactions are essentially reverse decomposition reactions, and decomposition reactions are reactions in which one or more elements or compounds are combined.

There are two categories of polar addition reactions. That is,

• electrophilic addition reactions
• Nucleophilic addition reactions

There are two categories of non-polar addition reactions:

• Radical addition reaction
• Cycloaddition reaction
