Study Notes
Lewis Structures and Molecular Geometries
- For OCl2, choose the optimal Lewis structure that represents the bonding and lone pairs.
- Electron geometry (eg) and molecular geometry (mg) for SiF4 are both tetrahedral, indicating a symmetrical shape.
- The compound formed from aluminum (Al) and oxygen (O) follows Lewis theory, resulting in the formula Al2O3.
- SO2 exhibits trigonal planar electron geometry, a bent molecular geometry, and is classified as polar due to its asymmetrical distribution of charge.
- CO2 has both electron geometry (eg) and molecular geometry (mg) as linear, reflecting its symmetrical linear arrangement.
Electronegativity Trends
- Electronegativity tends to increase when moving from left to right across a period on the periodic table, signifying greater ability of atoms to attract bonding electrons.
