Basics of Organic Chemistry question

2024 · 30 Jan · Shift 2 · Q3

JEE MainChemistryBasics of Organic ChemistryMCQ+4 / −1
Which among the following purification methods is based on the principle of "Solubility" in two different solvents?
  1. A
    Distillation
  2. B
    Sublimation
  3. C
    Column Chromatography
  4. D
    Differential Extraction
View written solutionFree

Correct answer: D

  1. We need the purification method that works on the basis of different solubility in two different solvents.

  2. Check each option:

    A. Distillation
    Distillation is based on difference in boiling points of components, not on solubility.

    B. Sublimation
    Sublimation is based on the ability of a solid to convert directly into vapour on heating. This depends on volatility/sublimability, not solubility.

    C. Column Chromatography
    Column chromatography separates substances based on different adsorption/partition between stationary and mobile phases. Though solvents are used, the basic purification principle is not simply solubility in two immiscible solvents.

    D. Differential Extraction
    Differential extraction is based on the different solubilities of a compound in two immiscible solvents. The solute distributes itself between the two solvents according to its relative solubility.

  3. Therefore, the correct option is:

D. Differential Extraction\boxed{\text{D. Differential Extraction}}D. Differential Extraction​

  1. Comparison with stored correct answer:
    Stored correct answer = D.
    Our derived answer = D.
    So they agree.
