Question:
The shape of XeF4 is: Square planar.
The shape of XeF4 is: Square planar.
Show Hint
XeF4: 4 bonds + 2 lone pairs. Lone pairs "sandwich" the square of Fluorines to keep it flat.
Updated On: May 5, 2026
- Tetrahedral
- Square planar
- See-saw
- Trigonal bipyramidal
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
The shape of a molecule is determined by the Valence Shell Electron Pair Repulsion (VSEPR) theory, considering both bonding and lone pairs of electrons.
Step 2: Meaning
Xenon ($Xe$) has 8 valence electrons. In $XeF_4$, it forms 4 bonds with Fluorine, leaving 4 electrons (2 lone pairs).
Step 3: Analysis
With 4 bonding pairs and 2 lone pairs, the steric number is 6, corresponding to an octahedral electron geometry. To minimize repulsion, the two lone pairs occupy opposite axial positions.
Step 4: Conclusion
The remaining 4 Fluorine atoms are arranged in a single plane around the central Xenon atom, resulting in a square planar molecular geometry. Final Answer: (B)
