Question

The polymer of which of the following molecule is found in non- stick coating of cookware?

• A. Ethene
• B. Tetrafluoroethene
• C. Vinyl chloride
• D. Isoprene

Answer 1

The correct option is B Tetrafluoroethene

Teflon is used in the making of non- stick coating of cookware. These polymers are formed when small ethene monomers combine together at high temperature and pressure in presence of catalysts. The reaction takes place as follows:

$\underset{\text{Tetrafluoroethene}}{{}^{n}C{F}_2=C{F}_2}\underset{\text{High Pressure, Catalyst}}{\overset{\text{High Temperature}}{\to }}\underset{\text{Teflon}}{{[C{F}_2-C{F}_2]}_n}$
