Name each of the three types of unsaturated hydrocarbons, summarize their structural differences, and give an everyday source of each.

Hydrocarbons are a type of organic compound. Hydrocarbons contains a carbon, hydrogen and oxygen bond that makes it organic. Chlorides, carbonates and nitrous oxides are not organic compounds but they are inorganic compounds.

The three types of unsaturated hydrocarbons are alkenes, alkynes, and aromatic hydrocarbons.

Alkenes contain at least one double bond, alkynes contain at least one triple bond, and aromatic hydrocarbons contain one or more benzene rings.

Sources of alkenes include margarine and rubber; a source of alkyne is acetylene fuel in welding torches; and sources of aromatic hydrocarbons are polystyrene and aspirin.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
