Which compound contains a triple bond?

There are many compounds which contain triple bonds between two atoms. Few of the are as follow,

Nitrogen Molecule:

                           N₂   or   :N≡N:

Cyanide Ion:

                          CN⁻   or    [:C≡N:]⁻

Alkynes:
                          R-C≡C-R

Carbon Monoxide:

                          CO    or    :C≡O:

Among given compounds Alkynes belong to a class of unsaturated hydrocarbons. The carbon atom in alkyne is sp hybridized. These unsaturated hydrocarbons have their own characteristic chemical properties.
