Chemistry The p-Block Elements NEET 2019

Match the Xenon compounds in Column-I with its structure in Column-II and assign the correct code:

Column-I

(a)

(b)

(c)

(d)

Column-II

(i) Pyramidal

(ii) Square planar

(iii) Distorted octahedral

(iv) Square pyramidal

Code:

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

Answer: (2)

Solution

Use VSEPR theory. (a) : 4 bond pairs + 2 lone pairs, octahedral electron geometry, shape square planar, so (a)-(ii). (b) : 6 bond pairs + 1 lone pair, shape distorted octahedral, so (b)-(iii). (c)
