QUESTION: 1

An example of biopolymer is              [1994]

Solution:

A Natural polymer which controls various life process in the body of a organism is called natural biopolymer.

DNA is a natural biopolymer which is a main constituent of chromosomes.

Rubber is a natural polymer but not a natural biopolymer.

QUESTION: 2

Bakelite is prepared by the reaction between          [1995]

Solution:

Phenol and formaldehyde undergo
condensation polymerisation under two
different conditions to give a cross linked
polymer called bakelite.

 

 

QUESTION: 3

In elastomer, intermolecular forces are [1995]

Solution:

Elastomers are the polymers having very
weak intermolecular forces of attraction
between the polymer chain. The weak forces
permit the polymer to be streched.

QUESTION: 5

Which one of the following is used to make "nonstick" cook-wares ?        [1997]
Solution:

We know that polytetrafluoroethylene or
teflon is a tough material, resistance to heat
and bad conductor of electricity. Therefore
it is used for coating the cookware to make
them non-sticky.

QUESTION: 6

Natural rubber is a polymer of        [1999]

hexamethylene diamine (6C).

It has high tenacity and elasticity. It is
resistant to abrasion and not affected by
sea water. It is used for reinforcement of
rubber tyres, manufacture of parachute,
safety belts, carpets and fabrics.
