Step 1I'll solve this step by step using proper Lewis structure drawing and polarity analysis:
Step 2: Determine Total Valence Electrons
- Total valence electrons: $$12 + 8 + 14 = 34$$ electrons
- Carbon (C): 4 valence electrons × 3 carbons = 12 - Hydrogen (H): 1 valence electron × 8 hydrogens = 8 - Chlorine (Cl): 7 valence electrons × 2 chlorines = 14
Final Answer
The molecule \text{C}_3\text{H}_8\text{Cl}_2 is polar due to the uneven distribution of electronegative chlorine atoms on one carbon.
