Identify which of the molecules below violates the octet rule.
I.ClF₃
II. SF₄
III.PCl₃
IV. SOCl₂

Question

Identify which of the molecules below violates the octet rule. I.ClF₃ II. SF₄ III.PCl₃ IV. SOCl₂

Quizplus · Accepted Answer

I and IV violate the octet rule. I (ClF) has an odd number of valence electrons, making it impossible to complete the octet for both atoms. IV (SOCl2) involves sulfur, which can expand its octet, but as described, it does not violate the octet rule. II (SF4) and III (PCl3) do not violate the octet rule; SF4 involves sulfur, which can expand its octet, and PCl3 adheres to the octet rule.
