Question

By using an expanded octen for the sulphur atom in thionyl chloride `(SOCl_(2)),` write a Lewis structure with no charge.

Answer 1

The structure of thionyl `(SOCl_(2)),` with expanded octet for sulphur is :
Formal Charge = Valence electrons `-("Shared electrons")/2-` Unshared electrons
Oxygen `=-4/2=0 ,"Sulphur "=6-8/2-2=0, "Chorine"=7-2/2-6=0`
Sonce none of the atoms has any formal charge,there is no formal charge on the molecule as a whole.
