Question

The molecular shapes of SF₄ , CF₄ and XeF₄ are 

(a) the same with 2, 0 and 1 lone pairs of electrons on the central atom respectively. 

(b) the same with 1, 1 and 1 lone pair of electrons on the central atoms respectively. 

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

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

Answer 1

(d) : SF₄ (sp³d, trigonal bipyramidal with one equatorial position occupied by 1 lone pair), CF₄  (sp³, tetrahedral, no lone pair), XeF₄ (sp³d₂, square planar, two lone pairs).
