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 _____________ × 10 - 1

Step-by-step solution

Given, an organic compound moved by 3 . 5 cm Solvent moved by 5 cm The R f (retardation factor) value is the ratio of the solute’s distance travelled to the solvent’s distance travelled. Retardation factor = Distance travelled by sample / organic compound Distance travelled by solvent By putting the values in the above formula, R f = 3 . 5 5 = 7 × 10 - 1
