Given below are two statements :
Statement I: Vapours of the liquid with higher boiling point condense before vapours of the liquid with lower boiling points in fractional distillation.
Statement II : The vapours rising up in the fractionating column become richer in high boiling component of the mixture.
In the light of the above statements, choose the correct answer from the option given below :
Statement I: Vapours of the liquid with higher boiling point condense before vapours of the liquid with lower boiling points in fractional distillation.
Statement II : The vapours rising up in the fractionating column become richer in high boiling component of the mixture.
In the light of the above statements, choose the correct answer from the option given below :
- (A)Both Statement I and Statement II are true
- (B)Both Statement I and Statement II are false
- (C)Statement I is true but Statement II are false✓ Correct
- (D)Statement I is false but Statement II are true
Answer: (C)
Solution
In a fractionating column the component with the higher boiling point reaches its condensation temperature sooner and condenses lower down, before the vapour of the lower-boiling component; the first statement is true. As vapour climbs the column it is repeatedly condensed and revaporised, and at each stage the higher-boiling component condenses and flows back while the lower-boiling component moves on, so the rising vapour becomes richer in the lower-boiling component, not the higher-boiling one; the second statement is false. The first statement is true and the second is false.
