D2sp3 hybridization?

Which of the following compounds exhibit d2sp3 hybridization? Select "yes" for molecules with d2sp3 hybridization and "no" for all others.

KrF4 --- yes
ICl5 --- yes
KrCl2 --- no
SF4 -- no
SeCl6 -- yes
PBr5 -- yes
IF3 -- no

can one tell me where i went wrong??

thank you advance

Answer:
Your mistake is only on PBr5. It is sp3d, not sp3d2.
d2sp3 hybridization creates six potential orbitals, enough for six single bonds or a combination of single, double or triple bonds and lone pairs to occupy six positions around the central atom.

Clearly, SeCl6 (six single) and PBr5 and ICl5 (five singles and a lone pair).

SF4 is sp3.

That brings me to Kr - I'm with you that KrCl2 is not, but wouldn't that also imply that KrF4 is not, too?

Guess I'm gonna have to brush up on hybridization.
