What is Cyclic compound?
In [[chemistry]], a '''cyclic compound''' is a [[molecule]] where some [[atom]]s are linked together forming a loop or ring. Most of the time, these molecules are [[organic chemistry|organic]]. There are also many examples of [[inorganic chemistry|inorganic]] molecule forming rings. Cyclic compounds can be [[aromatic hydrocarbon|aromatic]] - in this case they are flat. [[Benzene]] is a simple aromatic cyclic compound. When they are not aromatic, rings tend not to be flat to avoid [[steric effects]]. <gallery> Image:cycloheptane sticks.png|[[Cycloheptane]], a non-aromatic cyclic compound.

Many [[drug]]s are based on them, like [[aspirin]]. There are many [[chemical reaction|reactions]] that can make or break cyclic compounds. One important class of these is [[pericyclic reaction]]s. {{chem-stub}} [[Category:Chemical bonding]]
