Final answer:
XeF2 has a Lewis structure that is not consistent with the octet rule.
Step-by-step explanation:
The student's question is about identifying which molecule does not comply with 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, resulting in a noble gas electron configuration.
Among the given options, XeF2 is the molecule that has a Lewis structure not consistent with the octet rule. Xenon, a noble gas, can have an expanded valence shell, allowing it to accommodate more than eight electrons. In its compounds, such as XeF2, it can have more than eight electrons around it, which is an exception to the octet rule.
Therefore, the correct answer to the student's question is D. XeF2.
