The molecular shapes of \[\text{S}{{\text{F}}_{\text{4}}}\text{,}\,\text{Si}{{\text{F}}_{\text{4}}}\]and \[\text{ICl}_{4}^{-}\]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
\[ICl_{4}^{-}\]		\[s{{p}^{3}}{{d}^{2}}\]	two
