Among the following, the species having square planar geometry for central atom are: (i) \[{{X}_{e}}{{F}_{4}}\] (ii) \[S{{F}_{4}}\] (iii) \[{{[NiC{{l}_{4}}]}^{2-}}\] (iv) \[{{[PtC{{l}_{4}}]}^{2-}}\]
A) (i) and (iv)
B) (i) and (ii)
C) (ii) and (iii)
D) (iii) and (iv)
Correct Answer:
A
Solution :
\[{{X}_{e}}{{F}_{4}}\] In ground state In excited state \[S{{F}_{4}}\] is distorted trigonal bipyramidal structure \[{{[NiC{{l}_{4}}]}^{2-}}\] \[s{{p}^{3}}\] hybridisation tetrahedral structure. \[{{[PtC{{l}_{4}}]}^{2-}}.\] It is square planar in structure.
