A valid Lewis structure of ________ cannot be drawn without violating the octet rule. A)NF₃ B)IF₃ C)PF₃ D)SbF₃ E)SO₄^2-

Question

B) IF5 has 7 valence electrons from iodine and 5*7 from the five fluorine atoms, totaling 42 electrons. To accommodate all fluorine atoms, iodine expands its octet, which is possible because it is in the third period or below. However, the question implies a violation of the octet rule, which is not applicable here since heavier elements like iodine can expand their octet. This might be a misunderstanding of the question's intent, as none of the given compounds inherently violates the octet rule by necessity in their typical Lewis structures. Each of the other compounds can also adhere to the octet rule, with some expanding their octet where necessary.
