How boiling point is related to solubility?
greater the boiling point , lesser is the solubility
higher boiling point indicate the greater forces of attraction between the atoms of the molecule.
in that case when that compound is added to a solvent, then its solubility will be less because of the strong force of attraction between the atoms of the molecules of the compound. thereby making it difficult for the compound to dissociate within the solvent (hence less solubility)
