Step 1

As per the given figure the distance travelled by A is around 11 cm and the distance travelled by B is 4 cm. The solvent front travels 12.2 cm. The value of Rf can be calculated as,

Distance travelled by the solute
Distance travelled by the solvent front

Step 2

The values of Rf for A and B can...

For A
Distance travelled by the solute
Distance travelled by the solvent front
Rf
12.2
Rf 0.90
For B:
Distance travelled by the solute
Distance travelled by the solvent front
