ben•zene(ˈbɛn zin, bɛnˈzin)
a colorless, slightly water-soluble, liquid aromatic compound, C6H6, obtained chiefly from coal tar: used in making chemicals and dyes and as a solvent.
A clear, colorless, flammable liquid, C6H6. It is derived from petroleum and used to make detergents, insecticides, motor fuels, and many other chemical products. ♦ The six carbon atoms of benzene are arranged in a ring, called a benzene ring, having alternating single and double bonds, with a hydrogen atom attached to each carbon atom. This ring is a fundamental component of many other organic compounds.
Did You Know? One of the key insights in the history of chemistry came in a dream. In 1865 chemists knew that a benzene molecule consisted of six carbon atoms and six hydrogen atoms. They also knew that carbon atoms have four bonds by which they can join with other atoms. But none of the chain-like structures that chemists knew about then worked with these numbers of atoms and bonds. The German chemist Friedrich August Kekulé had thought about this problem for a long time. One night he fell asleep and dreamed of snakes. One snake bit its own tail, forming a circle. Awakened by the image, Kekulé realized that the six carbon atoms in benzene formed a ring. Each carbon was bound once to one adjacent carbon and twice to the carbon on its other side. And each used its fourth bond to hold a hydrogen atom outside the ring. Modern chemistry owes much of its power to the understanding of ringed carbon compounds that started with Kekulé's dream.
