Consider the molecules of furan and benzene. The dominant Lewis structure of furan and the two resonance structures of benzene are shown below: H K Book H What is the meaning of the double-sided arrow () connecting the two structures of benzene? Furan Benzene H It indicates that electrons in benzene rapidly change their positions corresponding to the two structures. It indicates that there are two independent coexisting forms of benzene. It indicates a chemical equilibrium between the two distinct structures. It indicates that the second structure can be obtained as a mirror image of the first one. It indicates that benzene exists in a single form, which is an average of the two structures.
