Question:
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 \( \_\_\_\_ \times 10^{-1} \).

Correct Answer: 7
Solution and Explanation
The retardation factor (Rf) is given by:
\(Rf =\frac{Distance\ travelled\ by\ sample/organic\ compound}{Distance\ travelled \ by \ solvent}\)
\(Rf=\frac{3.5}{5}=7 \times 10^{-1}\)
