EEJ MAIN Chemistry QUESTION #7155
Question 1
Identify the correct statements regarding silicones from the following: (a) They are hydrophobic polymers. (b) They are biocompatible. (c) They possess high thermal stability but low dielectric strength. (d) They are oxidation-resistant and used as greases.
  • (a), (b), (c) and (d)
  • (a), (b), and (c) only
  • (a) and (b) only
  • (a), (b) and (d) only✔️
Correct Answer Explanation
Silicones are organosilicon polymers.
  • They are hydrophobic due to alkyl groups.
  • They are biocompatible and used in medical implants.
  • They have high thermal stability and high dielectric strength (statement 'c' is incorrect because it says low dielectric strength).
  • They are resistant to oxidation and chemicals.
