Step 1:I'll solve this problem step by step, following the specified LaTeX and formatting guidelines:
Step 2:: Identify the Central Atoms
- In the skeletal structure HCCH, the carbon atoms are the interior atoms - We need to determine the molecular geometry for each carbon atom
Step 3:: Determine Electron Configuration for Carbon
- The hybridization will be $$sp$$ hybridization due to the triple bond
- Carbon has 4 valence electrons - In C^2H^2, each carbon forms multiple bonds
Step 4:: Analyze Bonding Arrangement
- Each carbon atom is bonded to:
Step 5:
One hydrogen atom
Step 6:
- Bond angle: $$180^{\circ}
One other carbon atom (triple bond) - This results in a linear molecular geometry
Step 7:: Sketch the Molecular Geometry
- The molecule will have a straight-line configuration - Hydrogen atoms on opposite ends - Carbon atoms connected by a triple bond
Step 8:: Confirm Molecular Geometry
- Linear geometry around each carbon atom - Total molecule is linear - Electron domain geometry matches molecular geometry
Final Answer
- Molecular Geometry: Linear - Bond Angle: 180^{\circ} - Hybridization: sp for each carbon atom
