Question

Which of the following compound(s) can form polymers?

• A. Propane
• B. Chloroethene
• C. Isoprene
• D. Tetrafluoroethene

Answer 1

Answer: (B), (C), (D)

The correct options are
B Chloroethene
C Isoprene
D Tetrafluoroethene

Polymerisation is a process in which large number of simple molecules (monomers) combine under suitable conditions to form complex molecules (polymers). This type of reactions occurs only in unsaturated hydrocarbons.
Propane contains only single bonds and cannot be polymerised. However, propene can be polymerised to polypropylene (PP).

Some of the common polymers for monomers are given below:

$\begin{array}{cc}\text{Monomer}& \text{Polymer}\\ \text{Chloroethene (Vinyl Chloride)}& \text{Poly vinyl Chloride (PVC)}\\ \text{2-methyl-1,3-butadiene (Isoprene)}& \text{Natural rubber}\\ \text{Tetrafluoroethene}& \text{Teflon}\end{array}$
