Step 1Let's solve this step by step:
Step 2: Understand Molecular Geometry Basics
Molecular geometry is determined by the number of electron domains (bonded atoms and lone pairs) around the central atom. The key is to count both bonded atoms and lone pairs.
Final Answer
Key Insights: - Tetrahedral electron geometry requires 4 total electron domains - The presence of a lone pair changes the molecular shape from tetrahedral to bent - Counting both bonded atoms and lone pairs is crucial in determining molecular geometry
