- In which option is the order showing whether the questions given below are true or false? () If the impurities are volatile, they can be separated according to the boiling point differences using the "Fractional Distillation" method. () If the liquid to be purified has a high boiling point, it should be done under low pressure so that the process can be carried out in a short time and does not decompose with high temperature. () Water vapor distillation is a technique used in the purification or separation of resinous substances that degrade at high temperatures. () In the crystallization process, the solubility of the substance to be purified in hot solvent should be very high, but it should not dissolve in cold and impurities should be at least moderately soluble in cold solvent.

Fractional Distillation: This lab was viewed via a video and described in detail in lab class. You are distilling apart hexane (bp = 68) and toluene (bp 110). Your boiling point for the first fraction is 48°C. Why is the boiling point so low (most likely reason)? !! azeotrope with water non-resonance of hexane O resonance of toluene student error O seriously impaired thermometerWe perform a 1.0 mL 2-methyl-2-butanol alcohol dehydration by simple distillation also using H2SO4.
