A compound consisting of long chainlike molecules, where the building units in the chain are monomers, is known as what?
Correct Answer:
Polymer
Explanation:
A polymer is a very long molecule built by linking many repeating units called monomers. The clue lies in the description of a long chain whose building blocks are monomers—the defining idea of a polymer. A monomer is just a single unit, so it cannot describe a long chain. An oligomer refers to a shorter chain, not a long one. A copolymer would be a polymer made from more than one kind of monomer, which isn’t specified here. So the best fit is polymer, with familiar examples like polyethylene, proteins, and DNA showing how monomers link to form long chains.
