Give the electronic and molecular geometries about the central atom for the following:

A) CH 4 B) XeF 6 2 +

hybrid = sp 3 hybrid = sp d^3 electronic geometry = tetrahedron electronic geometry = octahedral molecular geometry = tetrahedron molecular geometry = octahedral

C) (Note: check comments on multiple bonds) HCN D) CO 3 2 -

hybrid = sp hybrid = sp^2 electronic geometry = linear electronic geometry = trigonal molecular geometry = linear molecular geometry = trigonal

E) BCl 3 F) PCl 5

hybrid = sp 2 hybrid = sp d^3 electronic geometry = trigonal electronic geometry = trigonal pyramid molecular geometry = trigonal molecular geometry = trigonal pyramid

G) H O 2 H) NH 3

hybrid = sp 3 hybrid = sp^3 electronic geometry = tetrahedral electronic geometry = tetrahedral molecular geometry = bent 109 molecular geometry = trigonal pyramid I) SO 4 2 - ion J) IF molecule 5

hybrid = sp 3 hybrid = sp d^3 electronic geometry = tetrahedral electronic geometry = trigonal bipyramid molecular geometry = tetrahedral molecular geometry = trigonal bipyramid
