# How do you name benzene rings?

D is a special type of compound called a periacene. This one is named based on the "armchairs" and "zigzags" it has. For this one, it's called (5a, 3z)-periacene since it has five rows of benzene rings, each having an armchair ($\text{\""_""/}$), and three zig zags ($\hat{\text{ }}$). But you probably don't have to know this.
