  • ClO−3
  • XeF4
  • SF4
  • I−3
Show Solution

The Correct Option is D

Solution and Explanation

  • ClO−3: The central Cl atom has one lone pair.
  • XeF4: The central Xe atom has two lone pairs.
  • SF4: The central S atom has one lone pair.
  • I−3: The central I atom has three lone pairs.

Therefore, I−3 has the most lone pairs (3) on its central atom.
