Explore its structure
Choose a part to light it up.
Fluorine, chlorine, bromine or iodine bonded to carbon. Each pulls electrons toward itself, and each is larger than the hydrogen the carbon would otherwise carry.
From: standard chemistry.
Six carbons in a flat hexagon, sharing their electrons evenly around the ring. It is stable, flat and oily, and it stacks readily against other flat rings.
From: standard chemistry.
Rings joined where they share atoms, or a single ring standing alone. Atoms in a ring are held in place, so this part keeps its shape while chains around it can bend.
From: standard chemistry.
