What will happen if the upper outlet of the condenser is connected to the tap instead of the lower outlet?

उत्तर

  1. If water enters through the upper outlet of the condenser, the water will quickly flow down under the influence of gravity. This allows only a small section of the condenser to be cooled enough.
  2. If water enters through the lower outlet of the condenser, the entire condenser will be filled with water before it leaves out providing maximum cooling to the condenser. This results in the maximum recovery of purified liquid.
    Hence, water must be allowed to enter through the lower outlet of the condenser during the distillation process.

Define Distillation


Match the type of mixture of compounds in Column I with the technique of separation/purification given in Column II.

Column I Column II
(i) Two solids which have different solubilities in a solvent and which do not undergo reaction when dissolved in it. (a) Steam distillation
(ii) Liquid that decomposes at its boiling point (b) Fractional distillation
(iii) Steam volatile liquid (c) Simple distillation
(iv) Two liquids which have boiling points close to each other (d) Distillation under reduced pressure
(v) Two liquids with large difference in boiling points. (e) Crystallisation

Assertion (A): Simple distillation can help in separating a mixture of propan-1-ol (boiling point 97°C) and propanone (boiling point 56°C).

Reason (R): Liquids with a difference of more than 20°C in their boiling points can be separated by simple distillation.
