Other articles where Heteroatom is discussed: 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. 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 definition: any atom in the ring of a cyclic compound that is not a carbon atom Meaning, pronunciation, translations and examples. Unique heteroatom affinity and olefin affinity of the rare-earth metal ions together with the high olefin insertion activity of the rare-earth metal alkyls could promote the polymerization of heteroatom-containing a-olefins. Here, we report our studies on the heteroatom-assisted polymerization of a series of oxygen-, sulfur-, selenium. Six-membered rings with one heteroatom. The nomenclature used for the various monocyclic nitrogen-containing six-membered ring compounds is given below. Positions on the ring are shown for pyridine, Arabic numerals being preferred to Greek letters, although both systems are used.The pyridones are aromatic compounds because of contributions to the resonance hybrid from charged resonance forms.

(hĕt′ə-rō-ăt′əm)n.

An atom other than carbon or hydrogen in the structure of an organic compound, especially in a heterocyclic compound.

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…
