Question

Assertion (A): Silicones are used in surgical and cosmetic plants Reason (R): Silicones have high thermal stability

• (A) and (R) are correct. (R) is the correct explanation of (A)
• (A) and (R) are correct, but (R) is not the correct explanation of (A)
• (A) is correct but (R) is not correct
• (A) is not correct but (R) is correct

Hint:

- Silicones are preferred in medical and cosmetic applications due to their biocompatibility, non-toxicity, and chemical stability.
- Their thermal stability is an additional property but not the main reason for their use in these fields.

Answer 1

The Correct Option is B

Step 1: Check Assertion (A)

Silicones are used in medical and cosmetic fields due to their non-reactive nature and compatibility with living tissues.

(A) is true.

Step 2: Check Reason (R)

High thermal stability of silicones is due to strong Si-O bonds.

(R) is true.

Step 3: Logical link

Thermal stability is unrelated to their biological applications, so (R) does not explain (A).

Final Answer: \mathbf{(2)}
