Updated July 03, 2019 An aliphatic compound is a hydrocarbon compound containing carbon and hydrogen joined together in straight chains, branched trains or non-aromatic rings. Aliphatic compounds may be saturated (e.g., hexane and other alkanes) or unsaturated (e.g., hexene and other alkenes, as well as alkynes). The simplest aliphatic hydrocarbon is methane, CH4. In addition to hydrogen, other elements may be bound to the carbon atoms in the chain, including oxygen, nitrogen, chlorine, and sulfur. Most aliphatic hydrocarbons are flammable. Also Known As: aliphatic compound Examples of Aliphatic Hydrocarbons: ethylene, isooctane, acetylene List of Aliphatic Compounds Here is a list of aliphatic compounds, ordered according to the number of carbon atoms they contain.
