5 Multiple Choice 1 point Question: Why does phosphorus pentachloride

violate the octet rule? The molecule uses ionic bonding instead of covalent, removing the need for the octet. It forms resonance structures that prevent it from following the octet rule. Phosphorus can expand its octet by using d-orbitals, allowing five bonds instead of just four. Chlorine cannot share more than one electron, forcing phosphorus to break the rule.
