Abbreviation of Heteroatom Chemistry. The ISO4 abbreviation of Heteroatom Chemistry is Heteroat. It is the standardised abbreviation to be used for abstracting, indexing and referencing purposes and meets all criteria of the ISO 4 standard for abbreviating names of scientific journals. Heteroatom: In organic chemistry, an atom other than carbon or hydrogen. Acetamide (shown here) has two heteroatoms: one oxygen atom and one nitrogen atom. The carbon atoms and the hydrogen atoms are not heteroatoms.

Heteroatom Def
- In chemical compound: Functional groups
…carbon or hydrogen (termed a heteroatom) is bonded to carbon. All heteroatoms have a greater or lesser attraction for electrons than does carbon. Thus, each bond between a carbon and a heteroatom is polar, and the degree of polarity depends on the difference between the electron-attracting properties of the two…

Heteroatom Examples
- In heterocyclic compound
…to the noncarbon atoms, or heteroatoms, in the ring. In their general structure, heterocyclic compounds resemble cyclic organic compounds that incorporate only carbon atoms in the rings—for example, cyclopropane (with a three-carbon-atom ring) or benzene (with a six-carbon-atom ring)—but the presence of the heteroatoms gives heterocyclic compounds physical and chemical…
