Question

Correct statements among regarding silicones are:

(a) They are polymers with hydrophobic character.

(b) They are biocompatible.

(c) In general, they have high thermal stability and low dielectric strength.

(d) Usually, they are resistant to oxidation and used as greases.

Canvas Classes · Accepted Answer

Analysis of silicone properties:

(a) TRUE — Silicones are organosilicon polymers with hydrophobic (water-repelling) character due to the organic groups. ✓

(b) TRUE — Silicones are biocompatible and used in medical implants, prosthetics, etc. ✓

(c) FALSE — Silicones have high thermal stability ✓ but also high dielectric strength (good electrical insulators), NOT low. ✗

(d) TRUE — Silicones are resistant to oxidation and are used as greases, lubricants, and sealants. ✓

Answer: Option (4) — (a
