Match the interhalogen compounds of column-I with the geometry in column-II and assign the correct code.

  1. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
  2. (a)-(v), (b)-(iv), (c)-(iii), (d)-(ii)
  3. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
  4. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

Answer

(1) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Solution

(a) XX': diatomic ⇒ linear ⇒ (iii).

(b) XX'3: 3 bond pairs + 2 lone pairs (sp3d) ⇒ T-shape ⇒ (i).

(c) XX'5: 5 bond pairs + 1 lone pair (sp3d2) ⇒ square pyramidal ⇒ (iv).

(d) XX'7: 7 bond pairs (sp3d3) ⇒ pentagonal bipyramidal ⇒ (ii).

∴ (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
