Who was Friedrich Kelule? Chemist believed that the structure of molecules was unstable because reactions could disturb them. Kekule thought about the structure of benzene and one night had a dream about snakes. The snakes chased one another and one put his tail in its mouth. This Kekule believed to be a chain of 6 carbon atoms arranged in a ring. He believed that was the answer to the problem. Benzene is a 6carbon ringed compound with 6 hydrogen atoms. The carbon-carbon bonds were single and double. Kelule changed the way chemists viewed carbon bonds.
