Sec 1 Structure Physical Properties Discovery of Benzene Isolated in 1825 by Michael Faraday who determined C:H ratio to be 1:1. -Synthesized in 1834 by Eilhard Mitscherlich who determined molecular formula to be C6H6. -Other related compounds with low C:H ratios had a pleasant smell,so they were classified as aromatic.
