An organic compound containing carbon, hydrogen, and at least one triple covalent bond is called an alkyne.

Here's why:

* Alkanes contain only single bonds between carbon atoms.

* Alkenes contain at least one double bond between carbon atoms.

* Alkynes contain at least one triple bond between carbon atoms.

The simplest alkyne is ethyne, also known as acetylene (C₂H₂), which has a triple bond between the two carbon atoms.
