Draw the diagram/structures of the cyclic compound.

a.benzen

A benzene ring is a cyclic compound composed of 6 carbon atoms arranged in a hexagonal ring with alternate single and double bonds.

Here is the structure of benzene:

H
/ \
H-C -C-H
/ \
H H

Each carbon atom is bonded to one hydrogen atom, and there are alternating single and double bonds between the carbon atoms.

The diagram of benzene is typically drawn as a hexagon with a circle inside to represent the delocalized pi electron system.
