Explore its structure
Choose a part to light it up.
An O-H fixed directly to a benzene ring. The ring makes that hydrogen easier to give up than an ordinary alcohol's, which is why many phenols act as antioxidants.
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.
