Calculation of Rf Value
Rf value stands for the Retention Factor value, which is a ratio of the distance traveled by the compound to the distance traveled by the solvent front. It is a significant parameter used in Thin Layer Chromatography experiments to identify compounds.
Formula for Rf value is given as:
Rf value = Distance traveled by the compound / Distance traveled by the solvent front
In the given problem, the following data is given:
Distance traveled by the compound = 12.5 cm
Distance traveled by the solvent front = 18 cm
Substituting these values in the above formula, we get:
Rf value = 12.5 cm / 18 cm
Rf value = 0.694
Therefore, the Rf value for the compound is 0.694.

Rf=a/d
a=12.5cm, d=18cm
Rf=12.5/18=0.694
a=12.5cm, d=18cm
Rf=12.5/18=0.694
