A simple distillation was performed to separate a mixture containing both hexane and heptane. Explain why the observed starting vapor temperature in the simple distillation should be above the boiling point of hexane. Then, explain why if a fractional distillation was performed instead you would have a better separation (be sure to include how the fractionating column works in your explanation).

Which technique, recrystallization or distillation, would be most likely to separate each of these pairs? Explain your answers in complete sentences. Butylbenzene and 1-chloro-2,3,3-trimethylbutane Triiodomethane and 1-nitro-2-naphthol 2. For each pair, state whether you could get away with simple distillation or whether you would need fractional distillation. Explain your answers in complete sentences. ethylcyclohexane and bromocyclohexane cyclooctane and methyl acetate Is it possible to obtain pure (200-proof) ethanol, using fractional distillation, from a fermentation mixture that contains equal...

Someone please help me with this problem
Enantiomers have very similar physical properties,
while for diastereomers they can be very different. This fact is
important in the separation or resolution of enantiomers. In the
lecture, we looked at how chiral chromatography is used to separate
enantiomers: first, by reacting them with an optically pure chiral
reagent (i.e., pure R or S) to form a pair of diastereomers, then
separating them using chiral chromatography, and finally detaching
the chiral reagent to...

For lab we separated hexane and heptane using fractional and simple distillation. 4. Based upon your results, do you think you could separate a mixture of n-heptane and isopropanol (bp 82ºC)? Explain. Based upon your results, do you think you could separate a mixture of n-heptane and toluene (bp 115 ºC)? Explain.
