Question

Non-stick frying pans are coated black with Teflon, a material that is resistant to heat. Teflon is a polymer of:
A.Fluoromethane
B.Styrene
C.Ethylene
D.Tetrafluoroethylene

Answer 1

Hint: : Teflon or polytetrafluoroethylene is a synthetic fluoropolymer which can be obtained by the process of polymerization of a certain Monomer. Teflon could be found in the musical instrument lubrication product also it’s hydrophobic.

Complete step-by-step answer:Teflon can be prepared by the polymerization of tetrafluoroethylene

$nC{{F}_{2}}=C{{F}_{2}}\xrightarrow{Polymerisation}{{\left[ -C{{F}_{2}}-C{{F}_{2}}- \right]}_{n}}$

Polymerization is a process in which relatively small molecules known as monomers combine chemically to produce large chains like a network molecule called a polymer. Here the monomer unit used is tetrafluoroethylene.

Teflon is fluorocarbon solid which has a high molecular weight compound consisting of carbon as well as fluorine also it’s hydrophobic.
Teflon has one of lowest coefficients of friction of any of a solid.
It is non-reactive because of strength of carbon fluorine bond as well as so for because of quality use in containers along with pipework for reactive with corrosive chemicals.
Its major application in industry is its use for plain bearing, gear, slide plate, seal along with brushing. Thus, Teflon is polytetrafluoroethylene which is fluorocarbon and is non-reactive because of the strength of $C-F$ bonds.

Therefore, Option D is correct option i.e. Non-stick frying pans are coated black with Teflon, a material that is resistant to heat. Teflon is a polymer of tetrafluoroethylene.

Note: Never heat the Teflon, when overheated it can release mildly toxic fumes. Also sometimes things made of Teflon get deteriorated. Due to its high corrosion resistance it’s useful in a lab environment where it’s used for lining containers along with tubing for highly corrosive chemical example hydrofluoric acid which would dissolve glass containers.
