Because of this phenomenon, lone pairs are frequently unable to contribute electron density to aromatic rings.
Hydroquinone is able to stabilize radicals because it can undergo hydrogen abstraction and experience this other phenomenon. This phenomenon explains why phenol is a stronger acid than cyclohexanol. In the methoxy- substituent of anisole, this phenomenon is at odds with induction. Because of this phenomenon, lone pairs are frequently unable to contribute electron density to aromatic rings. This phenomenon also ensures that the carbonate ion has a charge of (*) -2/3, because its true configuration lies somewhere between the three namesake degenerate contributors. For 10 points, name this phenomenon in which a compound is stabilized because its electrons are delocalized, visualized by drawing double-headed arrows between multiple structures in brackets.
