Enumerate any two differences between simple distillation and fractional distillation.

Hint: Simple distillation and fractional distillation are two different types of processes. One can elaborate on the differences in the procedure these processes follow, which type of materials are processed, and some reaction set up related differences.

Complete answer:1) First of all we will learn what the distillation process is about. Distillation is a process that is used to remove impurities i.e. separating a pure liquid from a mixture by first heating and then cooling.
2) Now let's learn about the differences between simple distillation and fractional distillation.
A) Simple distillation:
i) Simple distillation has a very simple apparatus set up in which there is a need for two simple flasks, a burner, and a condenser.
ii) The process of simple distillation is used in the distillation of seawater.
iii) By using the simple distillation process one can use the liquids to separate which have a boiling point difference of more than fifty degrees Celsius.
B) Fractional distillation:
i) Fractional distillation has a very complex apparatus set up in which there is a need for complex apparatus such as fractionating columns.
ii) The process of fractional distillation is used for the distillation process in crude oil refining.
iii) By using the fractional distillation process one can use the liquids to separate which have boiling points difference very less.

Note:The fractional distillation is performed in multiple steps as a simple distillation process is carried in one step. The separation of liquid from a solid is generally performed by a simple distillation process. Simple distillation has only one simple step as vaporization by heat and condensation by making it cool.
