the stationary phase in TLC is a <u>silica gel coated metal plate or paper</u>.
The<u> individual</u> component of the mixure will travel a greater distance up the plate, resulting in a <u>Rf</u> value for the component.
the <u>p-Xylene spot </u> will travel a greater distance as it is the <u>lighter</u> component
Bromobenzene will travel least as it is the <u>heavier</u> component.
thin layer chromatography (TLC) is a type of chromatographic seperation technique that is based on the molecular size of components. the Rf value is the distance covered by the component relative to that travelled by the solvent which is the mobile phase
