Question

in the following species formal charge on central nitrogen atom is
(a) +1
(b) -1
(c) +2
(d) -2​

Answer 1

Answer:

+1 after the let the -1 between the 1

Answer 2

In the following species formal charge on central nitrogen atom is +1 (Option a)

• The formula to calculate formal charge (F.C.) on an atom in lewis structure is as follows
• F.C. =[Total number of valence electrons in the free atom] - [Total number of non-bonding electrons] - 1/2 [Total number of bonding electrons]
• N atom has 5 valence electrons and in NO2 it has 8 bonding electrons and no valence electrons.
• So, F.C. = [5 - 0- 1/2(8)]= [5 - 4] = 1
• Hence the formal charge on central atom is +1.
