Compound Lewis Structure (with dipoles) and Wedge-Hash Structure # of e groups Electronic Geometry Molecular Shape Bond angles Polar molecule? Hybridization XeF? SF? BrF? XeF? phosphate
The Correct Answer and Explanation is:
1. XeF2 (Xenon Difluoride)
- Lewis Structure: Xe in the center, two F atoms attached, and three lone pairs on Xe.
- # of e groups: 5 (2 bonding pairs, 3 lone pairs).
- Electronic Geometry: Trigonal bipyramidal (due to 5 electron groups).
- Molecular Shape: Linear (due to the three lone pairs, which cause repulsion to arrange the bonding pairs opposite each other).
- Bond Angles: 180°.
- Polar Molecule?: Yes, due to the lone pairs on Xe, leading to a dipole moment.
- Hybridization: sp³d.
2. SF6 (Sulfur Hexafluoride)
- Lewis Structure: S in the center with six F atoms attached, no lone pairs on S.
- # of e groups: 6 (all bonding pairs).
- Electronic Geometry: Octahedral.
- Molecular Shape: Octahedral.
- Bond Angles: 90° and 180°.
- Polar Molecule?: No, the symmetrical shape cancels out dipoles.
- Hybridization: sp³d².
3. BrF5 (Bromine Pentafluoride)
- Lewis Structure: Br in the center, five F atoms attached, one lone pair on Br.
- # of e groups: 6 (5 bonding pairs, 1 lone pair).
- Electronic Geometry: Octahedral.
- Molecular Shape: Square pyramidal (due to the lone pair).
- Bond Angles: 90° and 180°.
- Polar Molecule?: Yes, due to the asymmetry from the lone pair.
- Hybridization: sp³d².
4. XeF4 (Xenon Tetrafluoride)
- Lewis Structure: Xe in the center, four F atoms attached, two lone pairs on Xe.
- # of e groups: 6 (4 bonding pairs, 2 lone pairs).
- Electronic Geometry: Octahedral.
- Molecular Shape: Square planar (due to lone pairs).
- Bond Angles: 90° and 180°.
- Polar Molecule?: No, symmetrical shape.
- Hybridization: sp³d².
5. Phosphate (PO₄³⁻)
- Lewis Structure: P in the center with four O atoms attached, one double bond, and three single bonds with O atoms carrying negative charges.
- # of e groups: 4 (all bonding pairs).
- Electronic Geometry: Tetrahedral.
- Molecular Shape: Tetrahedral.
- Bond Angles: 109.5°.
- Polar Molecule?: No, the molecule is symmetrical.
- Hybridization: sp³.
