Answer : The molecular formula of cyanide is, [tex]CN^-[/tex] and Lewis structure of cyanide is shown below.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is, [tex]CN^-[/tex]
As we know that carbon has '4' valence electrons, nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in [tex]CN^-[/tex] = 4 + 5 + 1 = 10
The skeleton structure of the compound, C molecule act as a central atom and is bonded to N with one sigma-bond and two pi-bonds with one negative charge.
Hence, the molecular formula of cyanide is, [tex]CN^-[/tex] and Lewis structure of cyanide is shown below.
