An alkyne is one of the four main types of hydrocarbons. Alkynes must contain at least one carbon to carbon triple bond in their chain. Alkynes are true hydrocarbons, meaning they are made up of nothing but hydrogen and carbon.
Alkynes are based on the formula CnH2n-2, where
- C is Carbon.
- H is Hydrogen.
- n refers to the number of carbon atoms.
Alkynes are similar to Alkanes except they contain a triple bond between two carbon atoms instead of a double bond. When one carbon shares a triple bond with another, this limits the number of hydrogen which can be bonded (resulting in less hydrogen atoms per carbon atom).
The suffix -yne distinguishes alkynes from other hydrocarbons.
