In organic chemistry, an alkyne is an unsaturated hydrocarbon which has at least one carbon—carbon triple bond between two carbon atoms. The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula {Carbon}n{Hydrogen}2n-2. Alkynes are traditionally known as acety...
