Question

Which of the following is not true about polymers?

• A. Polymers are high molecular mass macro-molecules.
• B. Polymers may be of natural or synthetic origin.
• C. Condensation polymers are made up of one type of monomers only.
• D. They have high viscosity and do not carry any charge.

Answer 1

Answer: (C)

Condensation polymers are made up of one type of monomers only.

A) Polymers are high molecular mass macro-molecules made with a large number of repeating subunits.

B) Naturally occurring polymers - Silk, Wool, DNA, etc.

Synthetic polymers- Nylon, Polyethylene, Polyester etc.

C) Two bi-functional monomers are used in condensation polymerisation,

Example Nylon-6,6 is the polymer of Hexamethylenediamine + adipic acid

So this statement is false.

D) Polymers are large chain molecules so they have high viscosity. Since monomers of polymers are neutral, the overall polymer is also neutral.
