1. Draw the Lewis Structure:
* Sulfur (S) is the central atom.
* Oxygen (O) has 6 valence electrons.
* Hydrogen (H) has 1 valence electron.
* Connect the atoms with single bonds (sigma bonds) to satisfy the octet rule for each atom.
The Lewis structure looks like this:
```
O
/ \
H S O
\ /
O
```
2. Count the Sigma Bonds:
* S-O bonds: There are four single bonds between sulfur and oxygen, each contributing one sigma bond.
* O-H bonds: There are two single bonds between oxygen and hydrogen, each contributing one sigma bond.
Total Sigma Bonds: 4 (S-O) + 2 (O-H) = 6 sigma bonds
Therefore, sulfuric acid (H₂SO₄) has 6 sigma bonds.
