| Consider the following statements. |
| 1. Acrylic is a synthetic fibre made of acrylonitrile monomer. |
| 2. Cellulose is a natural polymer. |

| Which of statements) given above is/are correct? |
A) Only 1
B) Only 2
C) 2 and 3
D) All of these
Correct Answer: D
Solution :
[d] Acrylic fibres are synthetic fibres made from a polymer average molecular weight of Rs.100000 about 1900 monomer units. To be called acrylic in the US the polymer must contain atleast 85% acrylonitrile monomer. Acrylic is also called fabric. As it resembles silk, it is also called artificial silk.
