Choccamine and mintanol have Rf values of 0.81 and 0.21 respectively. What would the distance in centimetres (cm) between the two compounds be if the TLC was run on a TLC plate where the solvent front moved 8.9 cm from the baseline?

1 answer

Rf value = (distance by unknown/distance by solvent)
Substitute and solve for distance by the 0.81 material and the 0.21 material, then subtract one from the other to find the distance between them.
