Solution

Q.
Three organic compounds A, B, and C were allowed to run in thin layer chromatography using hexane and gave the following result (see figure). The $R_{f}$ value of the most polar compound is ______ $\times 10^{- 2}$ [2023]

Ans.
(25)

Organic compound C is more polar

$R_{f} = \frac{distance travelled by substance}{distance travelled by solvent}$

$= \frac{2}{8} = 0.25 = 25 \times 10^{- 2}$
