Step 1Let's solve this step by step using VSEPR (Valence Shell Electron Pair Repulsion) theory:
Step 2: Determine the number of valence electrons
- Total valence electrons: $$4 + 12 = 16$$ electrons
- Carbon (C): 4 valence electrons - Oxygen (O): 6 valence electrons × 2 = 12 valence electrons
Final Answer
Key Reasoning: - CO^2 has a central carbon with two double bonds to oxygen - No lone pairs on the central atom - Electron domains are maximally separated - Results in a linear molecular shape with a 180° bond angle
