21.1: Alkanes: Saturated Hydrocarbons - Chemistry LibreTexts
WebAlkanes are found in animal products, although they are less important than unsaturated hydrocarbons. One example is the shark liver oil, which is approximately 14% pristane (2,6,10,14-tetramethylpentadecane, C 19 H 40). They are important as pheromones, chemical messenger materials, on which insects depend for communication. WebLike alkanes, alkenes are another homologous series of hydrocarbons. Alkenes are unsaturated hydrocarbons with one or more carbon-carbon double bonds. This C=C double bond is the functional group that defines a molecule as an alkene. Alkenes have the general formula: C n H 2n. extract from rar file online
