1) Calculate the Rf value of a spot that travels 5.7 cm, with a solvent front that travels 13 cm. 2) A student spots an unknown sample on a TLC plate and develops it in pentane solvent. Only one spot, for which the Rf value is 0.05, is observed. Is the unknown material a pure compound? What can be done to verify the purity of the sample using thin-layer chromatography? 3) You try to synthesize n-hexyl bromide as a product...
