Verified By Collegedunia
The Correct Option is D
Approach Solution - 1
- ClO−3: Central Cl atom has 1 lone pair.
- XeF4: Central Xe atom has 2 lone pairs.
- SF4: Central S atom has 1 lone pair.
- I−3: Central I atom has 3 lone pairs.
Thus, I−3 has the maximum number of lone pairs (3) on its central atom.
