Alkanes occur widely in nature in different forms.These are the simplest hydrocarbons.The lower members(C1 to C4) are major constituents of the natural gas which is used as fuel in cooking, automobiles and in power generation plants.Some of the higher hydrocarbons(C6 to C8) are constituents of gasoline or petrol.Diesel contains different alkens C15 to C18. Waxe,that occur in nature as coating on green leaves contain C29 to C31 alkanes. Some alkanes possess exceptional biological activity. Undecane(C11 alkane) secreted by cockroach helps to attract opposite gender of its species. Cyclohexane, a cyclic alkane is one of the common component of mangoes. It is intended to study some interesting aspects of chemistry of alkanes in this chapter.
