 * **﻿Where Hydrocarbons Come From **
 * Hydrocarbons come from decayed plant and animal matter such as petroleum and coal.
 * Coal and petroleum are used for generating electrical energy.
 * They go through a process called fractual distillation. So every time you flip on a light switch, drive a car, or turn on hot water, you are using organic compounds.

 * A hydrocarbon that contains no multiple covalent bonds.

 * A heteroatom is any atom in an organic molecule other than carbon or hydrogen.
