Explain what happens to the boiling and solubility of alcohols as their chain length increases

Boiling point: As alkyl chain length increases, boiling point increases as there are surface area contacts and so stronger induced dipole-dipole intermolecular forces – more energy needed to overcome leading to a higher boiling pointSolubility: As alkyl chain length increases, the solubility of the alcohol decreases since the aliphatic chain can’t form H-bonds and that becomes the larger part of the molecule
