Question

What are the advantages of simple distillation over fractional distillation? Select all that apply. Select one or more: a. Less expensive. b. Requires lower pot temperatures. c. Requires less time. d. Gives better separation of methanol and water. e. Requires less energy.

Answer 1

simple distilation means : distilation of any organic solvents in pressence of suitable drying reagent and distilled at more than bioling pont

whereas fractional distillation is another techniques for purification of liquid mixture of sample wilth considerble bioling point difference

a) simple distillation is less expansive than fractional distilation

b) for fractional distilation it required low temprature flask, than for simple distilation heating mantle is required

c) simple distilation is time consuming process than fractional distilation

d) fractional distilation will give better separation of methanol and water because (difference between bioling points are more i.e 66 for methanol and 100 for water

e) simple distilation required more temrature than fractional distilation
