C07C ACYCLIC OR CARBOCYCLIC COMPOUNDS
Introduced: September 1968
Description
C07C covers the synthesis, preparation, and chemical composition of acyclic (open-chain) and carbocyclic organic compounds containing only carbon and hydrogen, or carbon, hydrogen, and non-metallic elements in their basic structure. This broad subclass encompasses hydrocarbons, alcohols, aldehydes, ketones, carboxylic acids, esters, and related derivatives of aliphatic and cyclic carbon skeletons. The classification explicitly excludes heterocyclic compounds (which contain atoms other than carbon in the ring structure), which are covered separately in C07D, and naturally occurring or isolated compounds typically classified elsewhere by their specific function or source.

Glossary
Acyclic the absence of a ring structure. Carbocyclic the presence of a ring or ring system where all ring members are carbons. Bridged the presence of two rings that share at least three ring members. Condensed the presence of two rings that share at least one ring member, e.g., spiro and bridged are considered as condensed. Condensed ring system condensed ring systems a ring system in which all rings are condensed among themselves; the "number of rings" in a condensed ring system equals the number of scissions necessary to convert the ring system into one acyclic chain. A scission is the breaking of a bond connection between two atoms irrespective of whether the bond is single or multiple. Organic compound Organic compounds compound satisfying one of the following criteria: at least two carbon atoms bonded to each other; or one carbon atom bonded to at least one hydrogen atom or halogen atom; or one carbon atom bonded to at least one nitrogen atom by a single or double bond. Exceptions to the above criteria are: compounds consisting of only carbon atoms (e.g., fullerenes, etc.), cyanogen, cyanogen halides, cyanamide, metal carbides, phosgene, thiophosgene, hydrocyanic acid, isocyanic acid, isothiocyanic acid, fulminic acid, unsubstituted carbamic acid, and salts of the previously mentioned acids; these exceptions are considered to be inorganic compounds for classification purposes. Preparation Preparations covers synthesis, purification, separation, stabilisation or use of additives, unless a separate place is provided in the classification scheme. Quinones quinone compounds derived from compounds containing a six-membered aromatic ring or a system comprising six-membered aromatic rings (which system may be condensed or not condensed) by replacing two or four >CH groups of the six-membered aromatic rings by >C=O groups, and by removing one or two carbon-to-carbon double bonds, respectively, and rearranging the remaining carbon-to-carbon double bonds to give a ring or ring system with alternating double bonds, including the carbon-to-oxygen bonds; this means that acenaphthenequinone or camphorquinone are not considered as quinones.
