n.
A hexagonal ring arrangement found in benzene and other aromatic compounds, consisting of six carbon atoms with alternating single and double bonds between them, and with each carbon atom bonded to a hydrogen atom, or to other atoms or groups of atoms in derivatives of benzene.

n.

The hexagonal ring structure in the benzene molecule and its substitutional derivatives, each vertex of which is occupied and distinguished by a carbon atom.

A carbon- and hydrogen-based molecule, which is made up of six carbons attached to each other by alternating single and double bonds, each attached to one hydrogen atom. If the structure is drawn, it becomes clear that the double bonds can exist alternatively on either side of any particular carbon atom as long as they alternate. In fact, the molecule does not possess a static structure, and the bonds do not exist as double and single bonds at any one site. As the electrons can exist on either side of any given atom of carbon, they form a continuous electron cloud, resonating from carbon atom to carbon atom. This electron cloud makes the molecule extremely stable. See Aliphatic.1.
