• # question_answer Molecular shapes of $S{{F}_{4}},C{{F}_{4}}$ and $Xe{{F}_{4}}$ are A)  Same with 2, 0 and 1 lone pairs of electrons respectively.B)  Same with 1, 1 and 1 lone pairs of electrons respectively.C)  different with 1, 0 and 2 lone pairs of electrons respectively.D)  different with 1,1 and 1 lone pairs of electrons respectively.

$S{{F}_{4}}$ ($s{{p}^{3}}\,\,\,d$ hybridisation, trigonal bipyramidal with one equatorial position occupied by 1 lone pair) $C{{F}_{4}}$ ($s{{p}^{3}},$ tetrahedral, no lone pair) $Xe{{F}_{4}}$$(s{{p}^{3}}{{d}^{2}},$square planar two lone pairs).
