What is the molecular geometry of CH4 according to VSEPR theory?
Correct Answer: Tetrahedral
- Step 1: Identify the molecule CH4, which is methane.
- Step 2: Count the number of hydrogen atoms bonded to the carbon atom. There are 4 hydrogen atoms.
- Step 3: Determine the number of bonding pairs. Each hydrogen forms a bond with carbon, resulting in 4 bonding pairs.
- Step 4: Check for lone pairs on the carbon atom. Carbon in CH4 has no lone pairs.
- Step 5: Apply VSEPR theory, which states that the shape of a molecule is determined by the number of bonding pairs and lone pairs.
- Step 6: Since there are 4 bonding pairs and no lone pairs, the molecular geometry is tetrahedral.
