Step 1Let's solve this step by step:
Step 2: Understand the Octet Rule
The octet rule states that atoms tend to combine in such a way that they each have eight electrons in their valence shell. Violations of this rule occur when an atom cannot achieve eight electrons through normal bonding.
Final Answer
ClF₃ Explanation: In ClF₃, the central chlorine atom would need to have 10 electrons to bond with three fluorine atoms, which violates the standard octet rule. This makes ClF₃ the molecule that cannot be drawn with a standard Lewis structure without expanding the octet.
