Answer :
Formal charge on C: (-1)
Formal charge on N: (0)
Net charge: (-1)
Explanation :
First we have to determine the Lewis-dot structure of
.
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, ![CN^-](https://tex.z-dn.net/?f=CN%5E-)
As we know that carbon has '4' valence electrons and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in
= 4 + 5 + 1= 10
According to Lewis-dot structure, there are 6 number of bonding electrons and 4 number of non-bonding electrons.
Now we have to determine the formal charge for each atom.
Formula for formal charge :
![\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%7D%3D%5Ctext%7BValence%20electrons%7D-%5Ctext%7BNon-bonding%20electrons%7D-%5Cfrac%7B%5Ctext%7BBonding%20electrons%7D%7D%7B2%7D)
![\text{Formal charge on C}=4-2-\frac{6}{2}=-1](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%20on%20C%7D%3D4-2-%5Cfrac%7B6%7D%7B2%7D%3D-1)
![\text{Formal charge on N}=5-2-\frac{6}{2}=0](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%20on%20N%7D%3D5-2-%5Cfrac%7B6%7D%7B2%7D%3D0)
Net charge = -1 + 0 = -1
