Organic Chemistry / Polymerisation 2017 O Level Pure Chemistry · Paper 1 · Q36

Question

Hydrocarbon Q, on heating with a catalyst, forms a solid compound, R. Both Q and R have the same empirical formula. What type of reaction is this?

Aaddition polymerisation
Bcondensation polymerisation
Chydrogenation
Dsubstitution

Correct answer: A

Video Solution

Explanation

Answer: A. A monomer and its addition polymer have the same empirical formula, because addition polymerisation simply joins the monomer units with no atoms lost.

The hydrocarbon Q (an alkene) forms a solid polymer R with the same empirical formula, so this is addition polymerisation.
