Chapter 7: Problem 48

This section contains multiple choice questions. Each question has 4 choices (a), (b), (c) and (d), out of which ONLY ONE is correct. Which among the following is a polymer? (a) Teflon (b) Pyrene (c) acrolein (d) Freon

Short Answer

Expert verified
a) Teflon b) Pyrene c) Acrolein d) Freon Answer: a) Teflon

Step by step solution

01

Teflon

Teflon is actually a brand name for a group of fluoropolymer material called polytetrafluoroethylene (PTFE). It is made by polymerizing tetrafluoroethylene monomers, and it is widely used for non-stick coatings, electrical insulation materials, and other applications. So, Teflon is indeed a polymer. Therefore, the correct answer would be Teflon.
02

Pyrene

Pyrene is a polycyclic aromatic hydrocarbon (PAH) comprised of four fused benzene rings. It is not a polymer because it is a single molecule, and it doesn't consist of monomers linked together. So, Pyrene is not a polymer.
03

Acrolein

Acrolein is an unsaturated aldehyde with the formula CH2=CH-CHO, and it is used as an intermediate in the production of acrylic acid. It is not a polymer because it isn't made up of repeating monomers. So, Acrolein is not a polymer.
04

Freon

Freon is a brand name for a group of chlorofluorocarbon (CFC) refrigerants. CFCs are not polymers, as they are small molecules and do not consist of repeating monomers. So, Freon is not a polymer. To conclude, the correct answer is option (a) Teflon, as it is the only option that is a polymer among the given choices.
