Question

1. Chlorination of ethylene is which type of reaction
a) Addition
c) substitution reaction
b) Elimination reaction
d) None of these.

​

Answer 1

Answer:

(a) Addition

 

Answer 2

Option (C) Chlorination of ethylene is a substitution  type of reaction.

Explanation:

• Chlorination of ethylene gives ethylene chloride.
• Here in this reaction, one hydrogen is replaced by one chlorine hence this is a substitution reaction.
• This reaction takes place between ethylene and chlorine.
• Ethylene chloride further undergoes reaction and forms vinyl chloride.
• Vinyl chloride further undergoes polymerisation reaction and forms poly vinyl chloride.
• Chlorination takes place in the presence of light
• Each hydrogen atom will be replaced by chlorine in steps.
