A colourless, sweet smelling, highly flammable liquid
Found naturally in crude oil, is a component of petrol and is also found in cigarette smoke
Classified as a carcinogen - can cause cancer
Evidence to disprove the Kekule model - the lack of reactivity of benzene
If benzene contained carbon=carbon double bonds it should decolourise bromine in an electrophilic addition reaction. However, benzene does not undergo electrophilic addition reactions. And benzene does not decolourise bromine under normal conditions. This has led to scientists to suggest that benzene cannot have any C=C bonds
