Apparently I missed one answer. What is the answer that I'm missing?

If 50mL of hexane (BP 69C ) and 50mL of decane (BP 174C ) are mixed together and distilled by simple distillation, which of the following are true? There are better ways to separate hexane and decane on this scale. The hexane will distill well, but it is impossible to distill anything at 174C The two compounds will be well separated, but there will be some loss in material for both. The two compounds will be well separated, and you'll be able to recovery 50mL of each when you are done. Hexane and decane cannot be separated well by distillation because both are alkanes and are liquids due to London dispersion forces
