Write Lewis structure or the following compounds and show formal charge on each atom . HNO_(3), NO_(2), H_(2)SO_(4) |
Answer» Solution :The Lewis structure of the FOLLOWING compounds and formal charge on each ATOM are as  Formal charge on an atom in a Lewis structure = (total number of valence electrons in free atom) - [total number of non-bonding (lonepairs) electrons) `(1)/(2)` [total number of bonding or shared electrons] (i) Formal charge on H = 1 - 0 - `(1)/(2) xx 2 = 0 ` Formal charge on `N = 5 - 0 - (1)/(2) xx 8 = 1`  Formal charge on O (1) = 6 - 4- `(1)/(2) xx 4 = 0 ` Formal charge on`O(2) = 6 - 4 - (1)/(2) xx ` 4 =0 Formal charge on O(3) = 6- 6 - `(1)/(2) xx 2 = - 1 ` (ii)Formal charge on O(1) = 6 -4 - `(1)/(2) xx 4 = 0 ` Formal charge on `N = 5 - 1 - (1)/(2) xx 6 = + 1 ` Formal charge on O(2) `6 - 6 - (1)/(2) xx 2= -1 ` (iii)  Formal charge on H(1) or H(2) = 1 - 0 - `(1)/(2) xx 2 = 0` Formal charge on O(1) or O(3)= 6 - 4 - `(1)/(2) xx 4 = 0 ` Formal charge on O(2) or O(4) = 6 - 6 - `(1)/(2) xx2 = -1` Formal charge on S = 6 - 0 - `(1)/(2) xx 8 = + 2 ` |
