What criteria does this mixture have to satisfy to be separated by simple or fractional distillation

Hi, the given question is incomplete, the complete question is:

You carry out a reaction that yields a major product Q (boiling point: 120°C) and side product R (boiling point: 150°C). The ratio of Q to R is 70:30. Both Q and Rare liquids.

After the ethyl acetate is evaporated, Q and R (a mixture of liquids) remain. What criteria does this mixture have to satisfy to be separated by simple or fractional distillation (besides bp difference and composition)?

The basic criteria are that the two liquids should be miscible. A mixture of two miscible liquids is further separated by the process of simple distillation and fractional distillation. For the liquids that exhibit varied boiling points, with a difference of +30 degrees C, the process of simple distillation is used. On the other hand, for the liquids whose boiling points come between the range of o to 30 degrees C, the process of fractional distillation is used.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
