JEE Main 2017 Chemistry question

Which of the following statements is not true about partition chromatography?

(1)Stationary phase is a finely divided solid adsorbent.Correct
(2)Separation depends upon equilibration of solute between a mobile and a stationary phase.
(3)Mobile phase can be a gas.
(4)Paper chromatography is an example of partition chromatography.

Answer: (1)

Solution

Partition chromatography separates components by **continuous differential partitioning** of each solute between two immiscible phases, both of which are fluids: a liquid stationary phase held on an inert solid support, and a mobile phase that flows past it. Check each statement against that definition. **(2)** is
