Quantrex Academy · Accepted Answer

Correct answer: B. A - IV, B - III, C - II, D - I

From the following lewis structures of IF _ 7 , ICl _ 4 ^ - , XeF _ 6 and XeF _ 2 : , , and we can deduce the number of lone pairs as well as the hybridisation of the central atom: cases IF _ 7 : & zerolonepair sp ^ 3 d ^ 3 ICl _ 4 ^ - : & twolonepair sp ^ 3 d ^ 2 XeF _ 6 : & onelonepair sp ^ 3 d ^ 2 XeF _ 2 : & threelonepair sp ^ 3 d cases
