Question

The shape of XeF₄ molecule according to VSEPR theory is:

RankGuru · Accepted Answer

1. **Determine the steric number**: Xenon ($Xe$) has 8 valence electrons.
- Number of bond pairs (BPs) = 4 (with F atoms)
- Remaining electrons = $8 - 4 = 4$ electrons (i.e., 2 lone pairs)
- Steric Number $= 4 + 2 = 6$
2. **Identify Geometry**: A steric number of 6 implies **Octahedral** electron pair geometry.
3. **Identify Shape**: To minimize lone pair-lone pair repulsion, the 2 lone pairs occupy opposite axial positions.
- The resulting molecular shape, formed only by the atoms, is **Square Planar**.
