In which of the following pairs, both the species have the same hybridisation-

(I) \[S{{F}_{4}},\,\,Xe{{F}_{4}}\]

(II) \[I_{3}^{-},\,\,Xe{{F}_{2}}\]

(III) \[ICl_{_{4}}^{+},\,\,\,SiC{{l}_{4}}\]

(IV) \[Cl{{O}^{-}}_{3},PO_{4}^{3-}\,\]

A) I, II                              

B) II, III

C) II, IV                

D) I, II, III

Correct Answer: C

Solution :

\[{{I}_{3}}^{-}\]                                 \[Xe{{F}_{2}}\] \[H=\frac{1}{2}(7+2+1)\]         \[H=\frac{1}{2}\left( 8+2 \right)\] \[=\,\,5\left( s{{p}^{3}}d \right)\]                       \[=\text{ }5\left( s{{p}^{3}}d \right)\] \[3\ell p\text{ }\And \,\,2b.p\]                   \[3\ell .p\text{ }\And \,\,2b.p.\,\]
