Answer 1

Answer:

Teflon of the following polymers is chemically least reactive and thermally most stable

Explanation:

Answer 2

Answer:

The correct option is (b).

Polytetrafluoroethylene (PTFE), also referred to as Teflon, is a substance that is used to coat nonstick cookware such as frying pans and saucepans.

Explanation:

• Because the Carbon-Flourine bond is so strong. Teflon is composed of only carbon and fluorine. It is resistant to other chemicals because it is not water or oil soluble, and its bonds are too strong for other chemicals to break.
• It is used in the production of nonstick cookware. It is used in the manufacture of an anti-friction device. It is used to coat medical devices (surgical devices). It is used for coating the lining of laboratory appliances due to its high corrosion resistance.
• Among all polymers, Teflon is a water-resistant, chemically inert material with a high electric conductivity and a very low coefficient of friction.
