Step 1I'll solve this systematically, focusing on molecular structure and polarity analysis.
Step 2: Analyze Electronegativity Differences
- Electronegativity difference: $$|2.20 - 1.90| = 0.30
- Silicon (Si) electronegativity: 1.90 - Hydrogen (H) electronegativity: 2.20
Final Answer
- Bond polarities: slightly polar - Molecular shape: tetrahedral - Molecule polarity: non-polar
