15.22—Rf values from one-way chromatograms in paper and thin-layer chromatography (TLC) and understand reasons for differences

Be able to calculate Rf values from one-way chromatograms in paper and thin-layer chromatography (TLC) and understand reasons for differences in Rf values.

Use —rf values from one-way chromatograms in paper and thin-layer chromatography (tlc) and understand reasons for differences to connect the rule to the data and decision in the question.

This matters because —rf values from one-way chromatograms in paper and thin-layer chromatography (tlc) and understand reasons for differences determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —rf values from one-way chromatograms in paper and thin-layer chromatography (tlc) and understand reasons for differences to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Rf values from one-way chromatograms in paper and thin-layer chromatography (TLC) and understand reasons for differences is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
