Question

Which one of the following polymers will not catch fire even at a high temperature of ${300}^{\circ }C$?

• A. $(-C{F}_2-C{F}_2-{)}_n$
• B. $(-C{H}_2-C{H}_2-{)}_n$
• C. $(-\underset{\underset{Cl}{|}}{CH}-\underset{\underset{Cl}{|}}{CH}-{)}_n$
• D. $(-C{H}_2-\underset{\underset{Cl}{|}}{CH}-{)}_n$

Answer 1

The correct option is A $(-C{F}_2-C{F}_2-{)}_n$

Teflon $(-C{F}_2-C{F}_2-{)}_n$ is stable upto 598K.
