Chemistry Organic Building Blocks Aliphatic Cyclic Hydrocarbons
Alicyclic compounds are a class of organic compounds that contain one or more rings composed of only carbon atoms, which can be either saturated or unsaturated, and lack the delocalized pi-electron system of aromatic compounds.
Alicyclic compounds can be categorized into monocyclic, bicyclic, and polycyclic compounds. The simplest alicyclic compounds are the monocyclic cycloalkanes, which include cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, and so on. Bicyclic alkanes, such as bicycloundecane, decalin, and housane, consist of two fused rings, while polycyclic alkanes, such as cubane, basketane, and tetrahedrane, contain three or more fused rings.
Alicyclic hydrocarbons are a class of organic compounds with some or all of their carbon atoms arranged in a cyclic structure. The ring structure can be saturated, meaning that all the carbon-carbon bonds are single bonds, or unsaturated, meaning that at least one carbon-carbon bond is a double or triple bond.
Cycloaliphatic hydrocarbons, also known as cycloalkanes, alicyclic hydrocarbons, or naphthenes, are a type of saturated hydrocarbon that contains one or more cyclic rings, each of which may be substituted with one or more alkyl side chains.
Alicyclic compounds containing three or four carbon atoms in the ring are less stable than those with larger rings, due to the smaller angles formed by adjacent covalent bonds. Larger rings, on the other hand, have all bond angles with the preferred value of approximately 109.5°, resulting in the atoms in the ring being non-planar.
