Question

At top, Image 1 shows 2 C's connected by 2 lines. Each C is connected by single lines to 2 H's. At bottom, two dots and 12 C's in a line, each connected to the others before and after with single lines. Each C is connected by single lines to 2 H's, 1 above and 1 below.
Which best describes what is represented by images 1 and 2?

Image 1 shows a polymer, and Image 2 shows a monomer.
Image 1 shows a monomer, and Image 2 shows a polymer.
Image 1 shows a macromolecule, and Image 2 shows a synthetic polymer.
Image 1 shows a synthetic polymer, and Image 2 shows a macromolecule.

Answer 1

Image 1 is a monomer (ethene, C2H4 — C=C with two H on each C). Image 2 is a polymer (a polyethylene chain: repeating –CH2– units).
