Question

Q no. 9: Why the Rf-value can not be more than one? Is there any unit for Rf value​

Answer 1

Answer:

==>Rf is a fraction. It is the ratio of how far a substance travels up the chromatography paper compared to the distance the solvent has travelled. This means that it must be less than 1.

Explanation:

==>The larger an Rf of a compound, the larger the distance it travels on the TLC plate. ... If two substances have the same Rf value, they are likely (but not necessarily) the same compound. If they have different Rf values, they are definitely different compounds.
