of unbonded electron repulsion. Examples:

a. Water, H 2 O

b. Ammonia, NH 3

4. sp^3 d^2 Hybrid Orbitals

These orbitals are formed from the hybridization of an s and a p

electron promoted to d orbitals and transformed into six equal

sp^3 d^2 orbitals. The spatial form is shown below. Sulfur

hexafluoride, SF 6 , illustrates this hybridization.
