The molecular shapes of\[S{{F}_{4}},C{{F}_{4}}\]and\[Xe{{F}_{4}}\]are     AIEEE  Solved  Paper-2005

A) different with 1, 0 and 2 lone pairs of electrons on the central atom, respectively

B) different with 0, 1 and 2 lone pairs of electrons on the central atom, 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 atom, respectively

Correct Answer: A

Solution :

Molecule	Structure	Hybridisation of central atom	Lone pair
\[S{{F}_{4}}\]		\[s{{p}^{3}}d\]	One
\[C{{F}_{4}}\]		\[s{{p}^{3}}\]	Zero
\[Xe{{F}_{4}}\]		\[s{{p}^{3}}{{d}^{2}}\]	Two
