Question

Assertion (A): Synthetic fibres have less water absorbing capacity.
Reason (R): They have hollow space in midst of a single fibre.
Choose the correct option.

• A. Both A and R are correct.
• B. Both A and R are incorrect.
• C. A is correct but R is incorrect.
• D. A is incorrect but R is correct.

Answer 1

The correct option is C A is correct but R is incorrect.

Synthetic fibres are made from chemical processes. E.g. polyester, nylon, etc.

Synthetic fibres do not have any hollow space in midst of single fibre. This doesn't allow water to settle in between spaces. Thus, they have less water absorbing capacity. Due to this property, synthetic fibres are used to manufacture raincoats.

Hence, assertion is correct but reason is incorrect.
