Question

$F_{2}C=C{F}_2$ is a monomer of

• A. teflon
• B. nylon
• C. glyptal
• D. buna- $S$

Answer 1

Answer: (A)

Teflon : Teflon is a polymer of tetrafluoratheylane. It is used for coating articles and cookware to make then non-sticky
$\underset{\text{Tetra fluoroethylene}}{n{F}_{2}C=C{F}_2}$ $\underset{\text{pressure}}{\overset{\text{Heat}}{\to }}$ — $\underset{\text{Teflon}}{(F_{2}C—C{F}_2{)}_n—}$
Nylon 66 : Nylon $66$ is a polymer of adipic acid and hexamethylene diamine. It is used in making bristles for brushes etc
$\underset{\text{Hexamethylene diamine}}{n{H}_{2}N(C{H}_2{)}_{6}N{H}_2}+nHOOC+\underset{\text{adipic acid}}{(C{H}_2{)}_{4}COOH}\to$

Glyptal : It is a polymer of etheylene glycol and phthalic acid. It is used in the manufacture of paints etc

Buna-S : Buna-$S$ is a polymer of butadiene and styrene
