An alkyne is a hydrocarbon that contains a triple bond. One or more carbon atoms are joined by the triple bond. One of which is a sigma bond, and the other two are pi bonds. Due to sp hybridisation, the 2 bonds either side of the triple bonded carbon atoms tend to be linear (at 180 degrees). The triple bond results in alkynes being more reactive but having lower stability. The most simplest alkyne is ethyne (acetylene). Alkynes have a specific property which makes them useful in everyday life - they burn readily in air.
