Passage

The polymer is a very large molecule that is made up of repeating small molecular units called monomers. The chemical reaction that unites the monomers is called polymerization. There are homopolymers, copolymers depending upon the type of monomers present in them.

Which of the following monomers will give radical polymerization most readily?
 

1. ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{CH}={\mathrm{CH}}_2$

2. ${\mathrm{CH}}_2={\mathrm{CH}}_2$

3. ${\mathrm{CH}}_3-\mathrm{C}\left({\mathrm{CH}}_3\right)={\mathrm{CH}}_2$

4. ${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2$

The polymer containing strong intermolecular forces like hydrogen bonding is

(1) Teflon

(2) nylon 6,6

(3) polystyrene

(4) natural rubber
