Answer:
Formal charge on n is +1
Formal charge on o is -1
Explanation:
Consider the atom n,
n is connected to o with a single bond and to c with a triple bond
<h3>Formula for formal charge on an atom is number of valence electrons - number of non-bonding electrons - (number of bonding electrons) ÷ 2</h3>
In case of n, number of valence electrons are 5
Number of non-bonding electrons are 0
Number of bonding electrons are 8 (∵ n is attached to 4 bonds and each bond is equivalent to 2 electrons)
∴ Formal charge on n = 5 - 0 - (8 ÷ 2) = 5 - 4 = +1
∴ Formal charge on n is +1
Consider the atom o,
o is connected to n by a single bond
In case of o, number of valence electrons are 6
Number of non-bonding electrons are 6 (∵ it has 3 lone pair of electrons)
Number of bonding electrons are 2 (∵ it is connected to n by a single bond and that bond is equivalent to 2 electrons)
Formal charge on atom o = 6 - 6 - (2 ÷ 2) = -1
∴ Formal charge on o is -1
