Step 2:: Understand Electron-Domain Geometry
Electron-domain geometry describes the arrangement of electron domains (bonding and non-bonding) around the central atom in a molecule.
Step 3:: Analyze CCl₄
For CCl₄: - Central atom is carbon (C) - Total electron domains = 4 (4 single bonds to chlorine atoms) - No lone pairs on the central carbon atom - Number of electron domains = 4 - Electron-domain geometry: Tetrahedral
Step 4:: Analyze PCl₃
For PCl₃: - Central atom is phosphorus (P) - Total electron domains = 4 (3 single bonds to chlorine atoms + 1 lone pair) - 1 lone pair on the central phosphorus atom - Number of electron domains = 4 - Electron-domain geometry: Tetrahedral
Step 5:: Select the Correct Answer
Based on the analysis: - CCl₄ has a tetrahedral electron-domain geometry - PCl₃ also has a tetrahedral electron-domain geometry
Final Answer
Tetrahedral Key Insights: - Electron-domain geometry depends on the total number of electron domains - Lone pairs count as electron domains - Tetrahedral geometry occurs when there are 4 electron domains around the central atom
