Question

Teflon, polystyrene and neoprene are all ________.

• A. copolymers
• B. condensation polymers
• C. homopolymers
• D. monomers

Answer 1

The correct option is C

homopolymers

• Homopolymers are addition polymers formed by the repetition of the exact same monomer unit. For example teflon $\left(\right({\mathrm{CF}}_2={\mathrm{CF}}_2{)}_n)$, polystyrene $\left(\right(C_8{H}_8{)}_n)$, neoprene$\left({\left({\mathrm{CH}}_2{\mathrm{CClCHCH}}_2\right)}_n\right)$, etc.
• Copolymers are also addition polymers. But, they are formed by two or more kinds of monomer units.
• Condensation polymers contain more than one functional group in them.
• Monomer units are the smallest repeating units that make up a polymer. However, teflon, polystrene and neoprene are polymers and not monomers.
