I am trying to determine the electron dot structure of an alkyne like $\ce{C2H2}$.


I know that hydrocarbons with at least one carbon-carbon triple bond are called alkynes, and their general formula is $\ce{C\_{n}H\_{2n-2}}$, where $n$ is number of carbon atoms.


So what will the electron dot structure of $\ce{C2H2}$ look like?




Carbon needs four electrons to fill its octet. In a $\ce{C-H}$ covalent bond carbon shares one electron with hydrogen. A triple consists of one σ covalent bond and two π covalent bonds. The carbons share two electrons in each of these bonds; in total six electrons are shared between them. You can draw this as a dot structure: 


$$\ce{H:C:::C:H}$$
