Alkyne is the series of unsaturated hydrocarbons containing a triple bond, including acetylene. Acetylene, also referred to as ethyne, is one of the most well-known and widely used alkynes.

Uses of Alkyne:

(i) In oxyacetylene flame
(ii) For the preparation of acetaldehyde, acetic acid and ethyl alcohol
(iii) For the manufacture of PVC, Polyvinyl ethers and neuprin rubber
(iv) As fuel.

If ethyne is passed through Fe pipe- heated at 400°C, polymerization of ethyne occurs & benzene is produced. The reaction is also occurs at -70°C in presence of Ni. Propyne produces Mesitylene.
