Hetrocyclic compounds
Dr.Mohammad A. R. Ismaiel
In organic chemistry, cyclic compounds that contain at least one ring atom that is not a carbon are called heterocycles. However, the rings of most heterocycles that pertain to organic chemistry contain more carbons than heteroatoms. However, "heterocycles" that do not contain any carbon, such as the ring, are also known in inorganic chemistry, but that is exactly why they are classified under inorganic chemistry.
