Question:
Which of the following set consists of only planar species?
Which of the following set consists of only planar species?
Show Hint
Planar species often arise from \(sp^2\) hybridization (trigonal planar) or \(dsp^2\) (square planar).

- XeF\(_4\), BF\(_3\), PCl\(_3\)
- XeF\(_4\), AlF\(_3\), NCl\(_3\)
- XeF\(_6\), BF\(_3\), AlCl\(_3\)
- XeF\(_4\), BF\(_3\), BCl\(_3\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Recall molecular geometries.
- XeF\(_4\): Square planar (due to 2 lone pairs on Xe).
- BF\(_3\): Trigonal planar (\(sp^2\)-hybridized).
- BCl\(_3\): Trigonal planar (\(sp^2\)-hybridized).
- PCl\(_3\), NCl\(_3\): Trigonal pyramidal (due to lone pairs) → not planar.
- XeF\(_6\): Distorted octahedral → not planar.
Step 2: Correct combination.
Only option (4) has all planar species: XeF\(_4\), BF\(_3\), BCl\(_3\).
Final Answer: \[ \boxed{\text{XeF\(_4\), BF\(_3\), BCl\(_3\)}} \]
