Heterocycles

    Of course atoms other than C can occur as part of the cyclic structure. Such atoms, which are known as heteroatoms, e.g. N, O, S give rise to heterocycles.  These heterocycles are, in general, very similar to the analogous hydrocarbons, check out the Chime images of a few common simple heterocylces and a few more complex natural heterocycles shown below.

Tetrahydrofuran 
(THF)
Pyrrolidine
Piperidine
Morpholine
