August Kekule von Stradonitz, original name Friedrich August Kekulé, (born Sept. 7, 1829, Darmstadt, Hesse—died July 13, 1896, Bonn, Ger. A total of three covalent bonds The remaining outer electron of each carbon is shared with the other carbons in the ring. See our User Agreement and Privacy Policy. Course: 0738―ORGANIC MATERIAL STRUCTURES The chemical formula for benzene is C6H6, i.e it has 6 hydrogen- H atoms and six-carbon atoms and has an average mass of about 78.112. Further chemical compounds that are manufactured using Benzene include detergents, pesticides insecticides, herbicides, and dyes.
