Question

Why the value of Rf is less than 1?

Answer 1

Rf values are alwaysless than 1. An Rf value of 1 or too close to it means that the spot and the solvent front travel close together and is therefore unreliable. This happens when the eluting solvent is too polar for the sample.

Answer 2

Rf value of 1or too close to it means that the spot and the solvent front travel close together and is therefore unreliable. This happens when the eluting solvent is too polar for the sample .
