Resonance in benzene is a concept derived from molecular orbital theory and is used to describe the delocalization of π (pi) electrons in the benzene ring. Unlike localized double bonds suggested by Kekulé’s structural hypothesis, resonance emphasizes the idea that the actual electronic structure of benzene is a combination of resonance hybrid of multiple contributing … Read more

The orbital picture of benzene provides a more accurate representation of its electronic structure than Kekulé’s model. In the orbital picture, resonance describes the distribution of pi electrons in the benzene ring. The key idea is that the pi electrons are delocalized and exist as clouds over all six carbon atoms, leading to a more … Read more
