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:.
Benzene has been measured in air inside vehicles at levels higher than those in residential air, zene contributes only a small peintake in non-smoking adults.World Health Organization (WHO) benzene gu
15-8. Benzene undergoes substitution reactions with electrophiles.. Electrophiles attack benzene by substituting for a hydrogen atom, not addition to the ring.. Under the conditions of this type of reaction, ordinary non-aromatic conjugated polyenes would polymerize rapidly..
