hydrocarbon is an organic compoundmade of nothing more than carbons and hydrogens. It is possible for double or triple bonds to form between carbon atoms and even for structures, such as rings, to form. Saturatedhydrocarbons have as many hydrogen atoms as possible attached to every carbon
Most hydrocarbons found on earth naturally occur in crude oil where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate at form seemingly limitless chains
