Whether compounds with zero R f value if developed with hexane are necessarily identical or not should be determined. Concept introduction: TLC or thin layer chromatography is technique that is used to separate various components of mixture with help of stationary phase and mobile phase. It makes use of silica gel, cellulose or aluminum oxide. This procedure is widely used because of its simplicity, low cost efficiency, and high sensitivity. Retention factor or R f refers to distance that is travelled by liquid to reach top of chromatographic plate. All compounds have particular value of R f for specific solvent. This value is used for comparison of unknown samples with known compounds.
