Chemistry

Electron Delocalization in Aromatic Compounds

Quick fact

In benzene, all six carbon–carbon bonds are exactly the same length — longer than a double bond but shorter than a single bond — because the electrons are equally shared across the whole ring.

Why this is interesting

You've probably seen benzene drawn with alternating double bonds, but the real molecule doesn't have them at all. So why do chemists still draw it that way?
