JEE Main 2026 Apr 6 Shift 2, Chemistry Q12: Purification Methods

JEE Main2026Apr 6, Shift 2Chemistry
Q.

Given below are two statements:

Statement I: A mixture of CHO (sugar) and NaCl can be separated by dissolving sugar in alcohol, due to differential solubility.

Statement II: Rose essence from rose petals is separated by steam distillation due to its high volatility and insolubility in HO.

In the light of the above statements, choose the correct answer from the options given below:

  1. A

    Both Statement I and Statement II are true

  2. B

    Both Statement I and Statement II are false

  3. C

    Statement I is true Statement II is false

  4. D

    Statement I is false Statement II is true

Solution

Sugar dissolves readily in ethanol whereas NaCl does not, so solvent extraction with alcohol cleanly separates them. Statement I is correct.

Rose oil is steam-volatile and immiscible with water — the classical situation where steam distillation (co-distillation at lower combined boiling point) is used. Statement II is correct.
