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
Definitions Conjugated double bonds are separated by one single bond. Example: 1, 3-pentadiene. Isolated double bonds are separated by two or more single bonds. 1, 4-pentadiene. Cumulated double bonds are on adjacent carbons. Example: 1, 2-pentadiene
