A polymer is formed from many what?

• A. Monomers
• B. Solvents
• C. Catalysts
• D. Polymers

Answer: (A)

A polymer is formed from many small molecules called monomers joined together to form a long chain. The term polymer literally means “many units,” and each monomer provides a repeating unit along the backbone of the polymer. This is why polymers like polyethylene come from many ethylene monomers linked together, while proteins are built from amino acids and DNA from nucleotides. Solvents aren’t part of the polymer’s structure; they simply help dissolve substances or carry reactants. Catalysts speed up the reaction but don’t become part of the polymer. So the building blocks are monomers, making them the correct concept.
