A. Tetra chloroethylene
B. Tetra bromethylene
C. Tetra iodoethylene
D. Tetra fluoroethylene

Answer

D

Explanation

Teflon is polytetrafluorine ethene (PTFE) is a polymer of tetrafluoro ethene `(CF_(2)=CF_(2))`
`underset("Tetrafluren ethylene")(nCF_(2)=CF_(2)) underset(Deltat, "pressure")overset((NH_(4))_(2)S_(2)O_(6))rarr [underset("Teflon")(-CF_(2)-CF_(2)-)]_(n)`
It is used in coating utensils to make them non sticking, making salts, gaskets which can with -stand high pressure, insulations for high frequency electrical installations.
