Chemistry / Unit 6 Chem 1107 short lesson, about 20 seconds
sp³d and sp³d² Hybridization
Captions available
The idea
sp³d hybridization mixes in one d orbital for a five-domain geometry, and sp³d² mixes in two d orbitals for a six-domain geometry, extending the same pattern past period 2.
In practice
Phosphorus in PCl5 is sp³d hybridized; sulfur in SF6 is sp³d² hybridized.
Where people slip
These d-orbital hybrids are limited to central atoms from period 3 and below, the same elements capable of an expanded octet.
