Question

espite the fact that XeO4 has a higher molecular mass than XeO3, XeO4 exists as a gas at room temperature, whereas XeO3 is a solid. Xe is the central atom in both molecules. Why is the boiling point of XeO3 so much greater?

XeO4 is a polar molecule, but XeO3 is non-polar.

XeO3 has a lone pair on both Xe and O atoms, but XeO4 has lone pairs only on O.

XeO4 has more double bonds than XeO3

XeO3 is a polar molecule, but XeO4 is non-polar.

XeO4 is a polar molecule, but XeO3 is non-polar.

XeO4 has more double bonds than XeO3

XeO3 is a polar molecule, but XeO4 is non-polar.

Explanation / Answer

XeO3 is polar molecule and XeO4 is non polar is correct and we know that boiling point is directly depend upon polARITY
