Write Lewis structure of the following compounds and show formal charge on each atom.

HNO₃, NO₂, H₂SO₄

Formal charge = valence electrons- (lone pair electrons + 1/2 bounded electrons)

(i) Formal charge calculations:

For N: 5 – 1/2 (8) = +1

For O: 6 – 6 – 1/2 (2) = -1

(ii) Formal charge calculations:

For N: 5 – 1/2 (8) = +1

For O without H: 6 - 6 - (1/2)2 = -1

For O without H on left side of N:6-4-1/2 (4)= 0

For O with H: 6 - 4 - (1/2)4 = 0

(iii) Formal charge calculations:

For S: 6 - (1/2)8 = +2,

For O without H: 6 - 6 - (1/2)2 = -1,

For O with H: 6 - 4 - (1/2)4 = 0.
