The best lewis structure for sulfuric acid has zero formal charges, sulfur as the central atom, and no bonds between s and h. how many single and double bonds, respectively, are there in this lewis structure?

If we are to draw the sulfuric acid structure based on Lewis it would look like:

O

ll

O = S - O - H

l

O

l

H

So from this, we can see that there are 2 double bonds (O = S) and 4 single bonds (S - O and O - H).

Therefore the answer is:

4 single, 2 double
