Match List - I with List - II.
- A-II, B-III, C-I, D-IV
- A-II, B-IV, C-I, D-III
- A-II, B-IV, C-III, D-I
- A-IV, B-III, C-II, D-I
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Purification techniques for organic compounds depend on physical properties like boiling point, volatility, and thermal stability.
Step 2: Detailed Explanation:
A. Simple distillation: Used for liquids that are stable at their boiling points and have a large difference in boiling points (typically $>25$ K). (Matches II).
B. Fractional distillation: Used to separate liquids whose boiling points are close to each other, employing a fractionating column. (Matches IV).
C. Steam distillation: Specifically used for substances that are steam volatile and immiscible with water (e.g., aniline). (Matches I).
D. Distillation under reduced pressure (Vacuum Distillation): Used for liquids that have very high boiling points or those that decompose at or below their normal boiling points (e.g., glycerol). (Matches III).
Step 3: Final Answer:
The correct matching is A-II, B-IV, C-I, D-III.

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
