###### FREE Expert Solution

We are asked to give the expected hybridization of the central atom for the molecules or ions.

Orbitals that can be used by the central atom:

Subshell                   Total # of orbitals

s             _                 1 orbital

p          _ _ _              3 orbitals

d        _ _ _ _ _          5 orbitals

POCl3

Valence electrons:

P → group 5A → 5 ve-

O → group 6A → 6 ve-

Cl → group 7A → 3 x 7 ve- = 21 ve-

Total = 32 ve-

# groups = 4 atoms = 4 groups

1 s orbital + 3 p orbitals  = 4 orbitals

s p p p= sp3

The hybridization of the central atom P is sp3

SO42-

Valence electrons:

S → group 6A → 6 ve-

O → group 6A → 4 x 6 ve- = 24 ve-

Total = 30 ve-

# groups = 4 atoms = 4 groups

1 s orbital + 3 p orbitals  = 4 orbitals

s p p p= sp3

The hybridization of the central atom S is sp3

XeO4

Valence electrons:

Xe → group 8A → 8 ve-

O → group 6A → 4 x 6 ve- = 24 ve-

Total = 32 ve-

# groups = 4 atoms = 4 groups

1 s orbital + 3 p orbitals  = 4 orbitals

s p p p= sp3

The hybridization of the central atom Xe is sp3
