The Correct Option is
Solution and Explanation
Concept:
Hybridisation is determined using steric number:
\[
\text{Steric number} = \text{bond pairs} + \text{lone pairs}
\]
Step 1: Find valence electrons.
Bromine (Br) has 7 valence electrons.
Step 2: Bond formation.
In BrF$_5$:
• 5 fluorine atoms form 5 sigma bonds → 5 bond pairs
• Remaining electrons = 2 → 1 lone pair
Step 3: Calculate steric number. \[ \text{Steric number} = 5 + 1 = 6 \]
Step 4: Determine hybridisation.
Steric number 6 corresponds to: \[ sp^3d^2 \]
Step 5: Geometry.
• Electron geometry → Octahedral
• Molecular shape → Square pyramidal (due to one lone pair)
Step 6: Final answer. \[ \boxed{sp^3d^2} \]
