Question

Following chromatogram was developed by adsorption of compound ' A ' on a 6 cm TLC glass plate. Retardation factor of the compound ' A ' is _____ × 10 - 1 .

TestHub · Accepted Answer

From the above picture of chromatographic plate, retardation factor is:
$R_{f} = \frac{Distance moved by the substance from base line}{Distance moved by the solvent from base line}$

$= \frac{3.0 cm}{5.0 cm} = 0.6$ or $6 \times 10^{- 1}$ .
