Formula of ethyne

`C_2H_2`

Electronic configuration of carbon

`1s^2 2s^2 2p^2`

Carbon has four valence electrons in the outermost shell.

Electronic configuration of hydrogen

`1s^1`

Hydrogen has one valence electron in the outermost shell.

Find the central atom in the compound

There are two carbon atoms attached to two hydrogen atoms, carbon atoms are the central atoms.

Structural formula of ethyne

Carbon atom requires four electrons to complete its octet and each hydrogen atom requires one electron to complete its octet.

Each carbon shares its one valence electron with one hydrogen atom, the remaining three valence electrons with another carbon atom and each hydrogen atom shares one valence electron with carbon atom.

There is one triple bond between two carbon atoms and a Single bond (covalent bond) is present between carbon and hydrogen atoms.
