What is Unsaturated Hydrocarbons?
Hydrocarbons containing one or more carbon-carbon multiple bonds (double or triple bonds). Alkenes contain at least one C=C double bond; alkynes contain at least one C≡C triple bond. Unsaturated hydrocarbons are more reactive than alkanes and can undergo addition reactions.

Frequently Asked Questions
Hydrocarbons containing one or more carbon-carbon multiple bonds (double or triple bonds). Alkenes contain at least one C=C double bond; alkynes contain at least one C≡C triple bond. Unsaturated hydrocarbons are more reactive than alkanes and can undergo addition reactions.
Ethylene (simplest alkene) is the most produced organic chemical, used to make polyethylene plastic. Propylene is used to make polypropylene. Unsaturated fatty acids in oils are nutritionally important. Acetylene (alkyne) is used in metal welding.
Many unsaturated hydrocarbons are flammable and their vapours form explosive mixtures with air. Prolonged exposure to aromatic unsaturated hydrocarbons like benzene causes serious health effects including leukaemia.
The formula or notation for Unsaturated Hydrocarbons is: C=C double bonds present; CₙH₂ₙ (alkene family)
