Reactions
of alkynes
Alkynes undergo hydration, halogenation, and hydrohalogenation just like alkenes.
A special application is the carbide
lamp (oxidation of alkyne).
2 C (coke) + CaO (lime) + heat
---> CaC2 (calcium carbide) + CO
CaC2 + H2O
---> H-CºC-H (acetylene) + Ca(OH)2
Acetylene serves as combustion fuel for
the carbide lamp.
