An alkyne is a molecule that has a triple bond between two carbon atoms. They have general formula CnH2n-2. They are also called acetylenes. The smallest alkyne is acetylene, also called ethyne. Alkynes are hydrophobic: this means they dissolve well in organic solvents but not in water. Each Successive members differs in its molecular formularity with "-CH2"
Alkynes are more reactive than usual hydrocarbons. For example, they are more reactive than alkenes in many reactions. If the alkyne is at the end of a molecule, it is easy to remove the proton with a strong base. Then, the alkyne can be used in addition reactions. For example, it can be added to a ketone. Alkynes are also easy to reduce to double bonds. They can be made into both trans and cis double bonds. Alkynes are also used a lot in pericyclic reactions.
