For this reason, organic compounds containing benzene rings were classified as being “aromatic” (sweet smelling) amongst scientists in the early 19th century when a relation was established between benzene derived compounds and sweet/spicy fragrances. Benzene is defined as a hydrocarbon, having the chemical formula as C 6 H 6.It contains six carbon atoms, which are joined in a ring and contain one hydrogen atom, which is attached to every carbon atom. By replacing either one or more of the hydrogen atoms with the functional group, we can avail many benzene compounds. You're going to love Organic Chemistry a lot more when you have this fun song!

Definition of benzene ring : a structural arrangement of atoms in benzene and other aromatic compounds that consists of a planar symmetrical hexagon of six carbon atoms which derives added stability from the delocalization of certain bonding electrons over the entire ring — compare meta- sense 4a, orth- sense 4b, para- entry 1 sense 2b Recall that in benzene and many other aromatic structures, a sextet of pelectrons is delocalized around the ring. When the molecule is exposed to B 0, these pelectrons begin to circulate in a ring current, generating their own induced magnetic field that opposes B 0. Benzene, C 6 H 6, is a planar molecule containing a ring of six carbon atoms, each with a hydrogen atom attached.
