Question:
What is shape of \(\mathrm{BrF}_5\) molecule?
What is shape of \(\mathrm{BrF}_5\) molecule?
Show Hint
Use VSEPR: count bond pairs and lone pairs on bromine.
Updated On: Nov 13, 2026
- Trigonal pyramidal
- Square planar
- Square pyramidal
- Bent ' \(T\) ' shape
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Bromine has 7 valence electrons. Five are used in bonds with fluorine, leaving one lone pair.
Step 2: Geometry
There are 5 bond pairs and 1 lone pair, so \( sp^3d^2 \) hybridisation and octahedral electron geometry.
Step 3: Shape
With one lone pair the shape is square pyramidal, option (C).
Final Answer:
BrF5 has a square pyramidal shape. \[ \boxed{\text{(C) }\text{Square pyramidal}} \]
