Answer : The correct option is, (3) 3
Explanation :
The given molecule is, Ethyne
As we know that ethyne is an unsaturated hydrocarbon which contains triple bonds between the carbon-carbon atoms.
In unsaturated compounds, there are less number of hydrogen bonded with the carbon atoms.
The formula of ethyne molecule is, [tex]C_2H_2[/tex]. In this molecule, there are triple bond is present between the two carbon atoms that means there are 3 pair of electrons present between the two carbon atoms.
Hence, there are 3 number of electron pairs that are shared between the two carbon atoms in a molecule of ethyne.
The structure of ethyne are shown below.
