#### In bisulphate ion, the formal charge on S atom is Option 1) +1 Option 2) +2 Option 3) +4 Option 4) +6

As we learnt in

Formal charge -

Formal charge is difference between the number of valence electron in an isolated atom and number of electrons assigned to that atoms in lewis structure.

- wherein

Formal Charge = Total number of valence electrons in free atom  (total no. of shared electrons)

In   ion, for S, we have

Valence electrons = 6

For structure 2, shared electrons = 8

Formal charge =

P.S. Formal charge will be different for structure 1 (o) but that is not provided in the options.
