Question

Assertion (A): Rayon is a semi synthetic polymer and is taken as a better choice than cotton fabric.

Reason (R): Mechanical and aesthetic properties of cellulose can be improved by acetylation.

• A. Both the assertion and the reason are incorrect statements.
• B. The assertion is an incorrect statement, but the reason is a correct statement.
• C. Both the assertion and the reason are correct statements, and the reason is the correct explanation for the assertion.
• D. Both the assertion and the reason are correct statements, but the reason is not the correct explanation of the assertion
• E. The assertion is a correct statement, but the reason is an incorrect statement.

Answer 1

The correct option is C

Both the assertion and the reason are correct statements, and the reason is the correct explanation for the assertion.

Assertion:

Rayon, also known as cellulose acetate, is a semi-synthetic polymer that has superior properties to natural cotton fibre.

Due to this, it is taken as a better choice than cotton fibre.

Hence, the assertion is a correct statement.

Reason:

The mechanical and aesthetic properties of cellulose can be improved by acetylation. Hence, Rayon, a product of acetylation of cellulose, has better properties than cotton.

Hence, the reason is a correct statement.

Both the assertion and the reason are correct statements, and the reason is the correct explanation for the assertion.

So, option (b) is the correct answer.
