WebThe factors affecting the boiling point are given below- Temperature – Temperature is responsible for increasing or decreasing the vapour pressure of the liquid. When the … WebThe solvent should have a boiling point that is at least 10 °C below the melting point of your solid sample. If the boiling point of the solvent is too close to the melting point of the sample, the solid may “oil out” of the solution. It is best to avoid highly toxic solvents such as carbon tetrachloride.
WebThe rule of thumb is that the stronger the intermolecular forces of attraction, the more energy is required to break those forces. This translates into ionic and polar covalent compounds having higher boiling and melting points, higher enthalpy of fusion, and higher enthalpy of vaporization than covalent compounds.
