WebbDuring a drug induced daze in 1858, Friedrick Kekule stumbled on his theory of the benzene structure and it seemed a simple solution to the mind boggling molecule of Mr 78. He proposed that six carbon atoms were joined by a ring of alternating double bonds and single bonds. Each carbon atom in benzene was bonded to a hydrogen atom and this … WebbNuclear Magnetic Resonance Spectroscopy.
