A benzene ring is a ring of . 6 carbon atoms. , each of which is also bonded to a hydrogen atom, with molecular formula . C. 15-4. The UV-visible spectrum of benzene reveals its electronic structure.. The energy gap between bonding and antibonding orbitals is greater in benzene than for acyclic trienes.. The UV spectra of benzene shows absorbances at smaller wavelengths (higher energy) than does the spectra of 1,3,5-hexatriene:. 6. th. Edition, Copyright . © John C. Hull 2005. 1. 8.. 1. Chapter 18.
