Biomolecules And Polymers — Part 1 MCQs with Explanations

Teflon , a common material in non-stick cookware and electronics, is a special type of plastic called a polymer . It's made of many small units linked together, like a chain. These small units contain carbon atoms . What makes Teflon special is the type of bond between these carbon atoms and another element. The question asks about this other element and the type of bond it forms with carbon. Option A: chloride - Chlorine can bond with carbon, but it doesn't form Teflon. Option B: fluoride - This is the correct answer! Teflon is actually polytetrafluoroethylene , which means it has many carbon-fluorine bonds. Option C: bromide - Bromine can also bond with carbon, but it doesn't create Teflon. Option D: iodide - Iodine can bond with carbon, but it's not the element that makes up Teflon. Therefore, the special bond in Teflon is a carbon-fluoride bond .
