Solution

Q.
On a thin layer chromatographic plate, an organic compound moved by 3.5 cm, while the solvent moved by 5 cm. The retardation factor of the organic compound is ____ $\times 10^{- 1}$ . [2024]

Ans.
(7)

Retardation factor ( $R_{f}$ ) = $\frac{Distance moved by organic compound}{Distance moved by solvent}$

$= \frac{3.5}{5} = 7 \times 10^{- 1}$
