Oreide

Oreide is a term that refers to a class of organic compounds derived from the hypothetical parent compound "ore" or, more commonly, the saturated hydrocarbon decane. These compounds are characterized by a core structure of ten carbon atoms arranged in a chain or a ring, with hydrogen atoms bonded to the carbons. In the context of organic chemistry, the term oreide itself is not a standard IUPAC nomenclature and is generally not used. Instead, specific compounds are named based on their precise structure and functional groups.

The most common and fundamental oreide is decane, a straight-chain alkane with the molecular formula C10H22. Decane exists as a liquid at room temperature and is a component of gasoline and kerosene. Branched-chain isomers of decane also exist, such as 2-methylnonane or 3-ethyl-2,4-dimethyloctane, each with distinct physical and chemical properties. Cyclic oreides, known as cyclodecanes, also belong to this family, featuring a ring of ten carbon atoms. These cyclic compounds are generally less common than their open-chain counterparts. The term oreide might sometimes be used informally to encompass any ten-carbon hydrocarbon, but precise naming conventions are crucial for accurate scientific communication.
