The molecular shapes of \[S{{F}_{4}},\,\,Si{{F}_{4}}\] and \[ICI_{4}^{-}\] are

A)  different with \[1,\,\,\,0\] and \[2\] lone pairs of electrons on the central atoms, respectively

B)  different with \[0,\,\,\,1\] and \[2\] lone pairs of electrons on the central atoms, respectively

C)  the same with \[1,\,\,\,1\] and \[1\] lone pair of electrons on the central atoms, respectively

D)  the-same with 2, 0 and 1 lone pairs of electrons on the central atoms, respectively

Correct Answer: A

Solution :

Molecule	Structure	Hybridisation of central atom	Lone pair
\[S{{F}_{4}}\]		\[s{{p}^{3}}d\]	one
\[Si{{F}_{4}}\]		\[s{{p}^{3}}\]	zero
\[ICI_{4}^{-}\]		\[s{{p}^{3}}{{d}^{2}}\]	two
