The separation of components of liquid on the basis of their boiling points is called as?
Correct answer: B. Fractional distillation
- A. Destructive distillation
- B. Fractional distillation
- C. Vacuum distillation
- D. Partial distillation
Explanation
Destructive distillation is a process that involves heating organic material in the absence of air or oxygen to break it down into simpler chemical compounds. Fractional distillation is a process used to separate a mixture of two or more liquids with different boiling points. This process relies on the fact that each liquid in the mixture has its own unique boiling point. Vacuum distillation is a type of distillation used to separate materials with high boiling points or those that are sensitive to heat. In vacuum distillation, the pressure inside the distillation apparatus is lowered, which reduces the boiling point of the material being distilled. There is no such term as partial distillation.

About Sublimation and Distillation
Sublimation separates a sublimable solid from non-sublimable impurities by direct conversion between solid and vapour, followed by deposition. Distillation separates liquids through differences in boiling points, including simple, fractional, steam and vacuum distillation, and the choice depends on volatility, miscibility and thermal stability.
