Updated On: Apr 13, 2026
- Linear , square planar
- Bent , square planar
- Bent , see-saw
- Linear , tetrahedral
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: For BrF\(_2^+\) ion.
BrF\(_2^+\) ion has 2 bond pairs and 2 lone pairs, which corresponds to \( sp^3 \) hybridization. This results in a bent geometry. Therefore, the geometry of BrF\(_2^+\) is bent.
Step 2: For BrF\(_4^-\) ion.
BrF\(_4^-\) ion has 4 bond pairs and 2 lone pairs, which corresponds to \( sp^3d^2 \) hybridization. This results in a square planar geometry. Therefore, the geometry of BrF\(_4^-\) is square planar.
Step 3: Conclusion.
Hence, the correct match for the geometry of BrF\(_2^+\) and BrF\(_4^-\) is bent and square planar respectively. The correct answer is (B). Final Answer: Bent, square planar.
