### VSEPR Worksheet

1. **Instructions:**
   - Draw the Lewis Structure
   - Circle any lone pairs
   - Name the electron geometry of the molecule
   - Name the molecular geometry of the molecule

2. **Molecule List:**
   - **CBr₄**
   - **C₂H₂**
   - **SO₃**

**Detailed Description:**

This worksheet aims to help students understand Valence Shell Electron Pair Repulsion (VSEPR) theory through practical examples. Students are required to:

1. **Draw the Lewis Structures** for the given molecules, which will help visualize how atoms are bonded within the molecule and the location of lone pairs of electrons.
2. **Circle any lone pairs** present on the central atom or atoms, as these influence the shape of the molecule.
3. **Name the electron geometry** of each molecule based on the total number of electron pairs (both bonding and lone pairs) around the central atom.
4. **Name the molecular geometry** using VSEPR theory, which describes the 3D arrangement of atoms in a molecule.

The molecules listed for this exercise include:
- **CBr₄ (Carbon Tetrabromide)** – a tetrahedral molecule with carbon as the central atom.
- **C₂H₂ (Acetylene or Ethyne)** – a linear molecule with a carbon-carbon triple bond.
- **SO₃ (Sulfur Trioxide)** – a trigonal planar molecule with sulfur as the central atom and double bonds to oxygen atoms.

Students are required to apply the VSEPR theory steps to these molecules to determine both their electron-pair geometries and molecular shapes.
