Match List - I with List - II : Choose the correct answer from the options given below.

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

Answer

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

Solution

(a) PCl5: 5 bond pairs, 0 lone pair (sp3d) ⇒ trigonal bipyramidal — (iv).

(b) SF6: 6 bond pairs, 0 lone pair (sp3d2) ⇒ octahedral — (iii).

(c) BrF5: 5 bond pairs, 1 lone pair (sp3d2) ⇒ square pyramidal — (i).

(d) BF3: 3 bond pairs, 0 lone pair (sp2) ⇒ trigonal planar — (ii).

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

Answer: (2)
