Question

what happens when ethylene is heated at high temperature under high pressure??give the chemical equation for the same,also name the reaction.
its a question of 3 marks

Answer 1

The reaction is called as Polymerisation.
When ethylene is heated under pressure in the presence of oxygen,a compound of high molar mass known as polyethylene or polythene is formed.

nCH2=CH2 -------------O2,Heat------------ (-CH2-CH2)n
                                                          Polythene

Answer 2

Answer:

Explanation:

C2h4+02 on heating gives co2+h2o

Balanced reaction

C2h4+302on heating gives 2co2+2h2o
