Step 1:I'll solve this step-by-step, following the LaTeX and formatting guidelines precisely:
Step 2:: Determine the central atoms and connectivity
- HCCH (ethyne) consists of two carbon atoms with hydrogen atoms attached - Carbon atoms will be connected by a triple bond - Each carbon will have one hydrogen attached
Step 3:: Count valence electrons
- Total valence electrons: $$8 + 2 = 10$$ electrons
- Carbon: 4 valence electrons × 2 = 8 electrons - Hydrogen: 1 valence electron × 2 = 2 electrons
Step 4:: Arrange atoms
\text{H} - \text{C} \equiv \text{C} - \text{H}
- Place carbons in a linear arrangement - Attach hydrogens to terminal carbons
Step 5:: Form bonds
- Create a triple bond between carbons (3 electron pairs) - Single bonds between carbons and hydrogens (1 electron pair each)
Step 6:: Distribute remaining electrons
- All electrons are used in bonding - No lone pairs remain
Final Answer
The Lewis structure for ethyne (HCCH) is a linear molecule with a triple bond between carbons and single bonds to hydrogen atoms: \text{H} - \text{C} \equiv \text{C} - \text{H}
