Passage / Comprehension

Column-I species	Column-II Related to species of Column I	Column-III Related to species of Column I & II
(P) $PCl_{5} (s)$	(1) $NO_{2}^{\oplus} + NO_{3}^{⊖}$	(i) square planar
(Q) $XeF_{4}$	(2) $PCl_{4}^{\oplus} + PCl_{6}^{⊖}$	(ii) Hybridisation of central atom in cationic part is sp & anionic part is $s p^{2}$
(R) Carbon monoxide	(3) $sp^{3} d^{2}$ , total lone pair = 14	(iii) Gas at normal temp.
(S) $N_{2} O_{5} (s)$	(4) Co-ordinate bond	(iv) Hybridisation of central atom in cationic part is $sp^{3}$ & anionic part is $sp^{3} d^{2}$

Which of the following matched is correct?

Options:

Answer:

Solution:

XeF₄ (Q): Central Xe has 4 bond pairs and 2 lone pairs, giving it an sp³d² hybridization and a square planar geometry (i). Lone Pairs: Total lone pairs = $2 (o n X e) + 4 \times 3 (o n e a c h F) = 14$ lone pairs, perfectly matching condition (3).

PCl₅(s) (P): Exists as $[PC l_{4}]^{+} [PC l_{6}]^{-}$ , matching with (2) and (iv) where the cationic part is sp³ and the anionic part is sp³d².

N₂O₅(s) (S): Exists as $[N O_{2}]^{+} [N O_{3}]^{-}$ , matching with (1) and (ii) where the cationic part is sp and the anionic part is sp².
