Complete the following paragraph.
the stationary phase in tlc . therefore, the of the mixture will travel a greater distance up the plate, resulting in value for the component.
when separating a mixture containing bromobenzene and p-xylene, the would be expected to travel the greatest distance up the plate as it is component. the would travel the least distance as it is component

Explanation:

the stationary phase in TLC is a silica gel coated metal plate or paper.

The individual component of the mixure will travel a greater distance up the plate, resulting in a Rf value for the component.

the p-Xylene  spot will travel a greater distance as it is the lighter component

Bromobenzene will travel least as it is the heavier 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
