    Fractional distillation is suitable for separation of miscible liquids with boiling point difference of about 25 K or less. What part of fractional distillation apparatus makes it efficient and possess an advantage over simple distillation process? Explain using a diagram.   [NCERT Exemplar]

Answer:

               The fractionating column packed with glass beads provides a surface for the vapours to collide and lose energy so that they can be quickly condensed an distilled. Also, length of the column would increase the efficiency of separation.
