Chapter 8, Problem 12Q
Interpretation Introduction

Interpretation:

The Rf value for substance B in figure 8.10 should be calculated.

Concept introduction:

The Rf value or the retention factor is defined as the ratio of distance traveled by the spots by the distance traveled by the solvent.

  Rf=Distance travelled by spotDistance travelled by solvent

The more the compounds move, the higher is the Rf value. Thus the polarity of the compound helps in deciding the Rf value.
