Question

Choose the incorrect match.
I. Rayon-wood pulp
II. Cotton and jute-biodegradable
III. Nylon-parachutes and stockings
IV. Melamine-catches fire easily

• A. IV only
• B. II & III
• C. III only
• D. None of the above

Answer 1

The correct option is A IV only

$\bullet$ Rayon is prepared by using wood pulp which is converted into a soluble compound.

$\bullet$ Cotton and jute are biodegradable because they can be decomposed easily by the action of microorganisms.

$\bullet$ Nylon is a strong fibre that can hold heavy weight so it is used for making parachutes and stockings.

$\bullet$ Melamine is thermosetting plastic that does not melt down on heating or catches fire easily so it is used for making clothes for firemen.

Hence the only incorrect match is IV.

Option A is correct.
