Answer:
The given condition is proved.
Explanation:
Given that,
Construct the resonance structure for CSO, which has a formal charge of +2 on the central atom and +1 on the oxygen atom.
We need to construct the resonance structure for CSO
The structure shown in figure
According to question,
A formal charge of +2 on the central atom and +1 on the oxygen atom.
Then tha structure shown in figure
The central atom in the structure is sulphur.
We need to calculate the formal charge on sulphur
Using figure,


A formal charge of +2 on the central atom.
This is proved.
Hence, The given condition is proved.
