Benzene Series. CnH2n-6. Benzene-C6H6. Benzene is hydrocarbon made up of 6 carbons and 6 hydrogen atoms. If forms a six sided ring. It was once believed to be a structure that had alternating double and single bonds.If this were the case, the bond lengths would be longer for the single bonds and shorter for the double.However this is not the case.enzene Series.
