🤓 Based on our data, we think this question is relevant for Professor Welch's class at UVA.

Solution: Two different compounds have the formula XeF2Cl2. Write Lewis structures for these two compounds, and describe how measurement of dipole moments might be used to distinguish between them.

Problem

Two different compounds have the formula XeF2Cl2. Write Lewis structures for these two compounds, and describe how measurement of dipole moments might be used to distinguish between them.

Solution

Xenon (EN = 2.60) is less electronegative than fluorine (EN = 3.98) and chlorine (EN = 3.16) so xenon is the central atom. We then need to count the total number of valence electrons for each element:

Fluorine and chlorine prefers to form 1 bond. There are two possible Lewis structures for this compound:
