Explain why AsF5 does not follow the octet rule? How/why are there exceptions to the octet rule?
Confused as to why certain structures can have an exception to the octet rule, such as trigonal bipyramidal and octahedral.

1 Answer
empty d orbitals, that's why
Explanation:
Arsenic has a noble gas configuration of:
Since arsenic has n=4, then it has angular momentum quantum numbers in this shell of 0, 1, 2, 3,
so you'd never write the electron configuration like this
Basically these empty d orbitals can get involved in the hybridization process
