Which statement provides the best explanation for the boiling points of the two isomers shown below?
Both isomers have the same boiling point because they have the same molecular formula. Isomer A has a higher boiling point because it is polar, and isomer B is nonpolar. Isomer A has a higher boiling point because the London dispersion forces between molecules are stronger. Isomer B has a higher boiling point because there are formal charges on the Cl atoms that cause attractive interactions.
