The hydrocarbon we know at present days as benzene was first isolated in 1825 by English scientist Michael Faraday. He made some experiments on an oily film derived from the lightning gas and discovered the new compound with the equal number of carbons and hydrogens in its structure. Faraday named his discovery bicarburet of hydrogen, […]
