A hydrocarbon is an organic compound made of nothing more than carbons and hydrogens. Hydrocarbons are soluble in oils but not water and are found in petroleum and other natural places. They lend themselves well to making other molecules.t is possible for double or triple bonds to form between carbon atoms and even for structures, such as rings, to form. Saturated hydrocarbons have as many hydrogen atoms as possible attached to every carbon. For carbons on the end of a molecular chain, three can be attached.
Hydrocarbons that contain rings or double bonds are called unsaturated hydrocarbons, which are the opposite of saturated hydrocarbons. Alkanes-such as cyclohexane, which is an important precursor to nylon-that contain rings of carbon atoms are unsaturated. Another example of a hydrocarbon is ethylene.ydrocarbons with carbon-carbon double bonds are called alkenes. Hydrocarbons with carbon-carbon triple bonds are called alkynes. And hydrocarbons that contain rings of carbon atoms that are joined by alternating single and double bonds are called aromatic.
