1
Identification of Monomers
Description:
Polymers are formed from small repeating units known as monomers. One of the most popular question asked from this chapter is related to the identification of monomer(s) from a given polymer.
How to Approach:
Monomers of homo polymers are very easy to remember and recall as it involves a single molecule from the which is obtained.

Monomers of co-polymers are a challenge as they involve two molecules which polymerise to give a polymer.

Uses of Polymers
Description:
Examiners ask many questions from this pattern of problems and students are often found unprepared. The questions are generally simple where you may have to identify the monomer or polymer from the given data on the uses of polymers. Or you may get a direct question where you are asked to write down the uses of a particular polymer.
How to Approach:
Try to remember the uses of some important polymers like Bakelite, PVC, etc.

Mechanism of Polymerisation
Description:
Many questions are asked from this pattern. Examiners can ask you to explain the mechanism of a polymerisation reaction or identify the polymer prepared by the given mechanism.
How to Approach:
Try to remember mechanism for addition and condensation reactions and also the types of polymers that are prepared from it.
