Write Lewis structure of the following compounds and show formal charge on each atom.HNO_{3},NO_{2},H_{2}SO_{4}

Answers (1)

The formula for calculation of the formal charge is as follows: -

Formal charge = ½ [total no: of bonding or shared electrons]

Oxygen with single bond will have formal charge of = 6-6-2/2 = -1

Oxygen with double bond will have formal charge of = 6-4-4/2 = 0

Therefore, nitrogen will have a formal charge of = 5-2-6/2 = 0

Oxygen 1 and 4 will have a formal charge = 6-4-4/2= 0

Oxygen 2 and 3 will have a formal charge = 6-4-4/2=0

Hydrogen 1 and 2 will have a formal charge = 1-0-2/2=0

Sulfur will have a formal charge =6-0-12/2 = 0

i) HNO3

ii) NO2

iii) H2SO4
