Unsaturated Hydrocarbon
Contain carbon-to-carbon double or triple bonds.
Unsaturated hydrocarbons are a class of organic molecules that contain at least one carbon double or triple bond in their structure. These types of hydrocarbons are known for their reactivity and chemical diversity, due to the presence of the double or triple bond which can undergo addition, elimination, or substitution reactions.
Examples of unsaturated hydrocarbons include alkenes, alkynes, and aromatics. Alkenes, such as ethene and propene, contain at least one carbon-carbon double bond. Alkynes, such as ethyne and propyne, contain at least one carbon-carbon triple bond. Aromatics, such as benzene and toluene, contain a ring of carbon atoms with alternating double bonds.
Unsaturated hydrocarbons often exhibit different physical and chemical properties than their saturated counterparts. For example, they may have lower melting and boiling points, and tend to be more reactive towards other molecules. Additionally, unsaturated hydrocarbons are important in the production of many useful chemicals, such as plastics, pharmaceuticals, and fuels.
