Certain simple molecules violate the octet rule
Certain simple molecules and ions, such as hypervalent species, violate the traditional octet rule by accommodating more or fewer than eight valence electrons.
The claim is that certain simple molecules violate the octet rule. Paper [5] directly supports this by examining hypervalent anions (like HF-) as exceptions to the octet rule. Paper [10] also discusses systems involving hypervalent and hypovalent atoms. Thus, the evidence clearly supports the claim.
