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.
We normally separate unreacted hydrogen from ammonia (product) in Haber process. The reaction mixture contains some ammonia, plus a lot of unreacted hydrogen and nitrogen. The mixture is cooled and compressed, causing the ammonia gas to condense into a liquid.
