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 $\qquad$ $	imes 10^{-1}$.\

Professor PC Thomas Classes · Answer

(7) : The retardation factor $\left(R_{f}ight)$\ $=\frac{	ext { distance travelled by organic compound }}{	ext { distance travelled by solvent }}$\ $=\frac{3.5}{5}=0.7=7 	imes 10^{-1}$\
