Answer 1

Rf value is also known as the retention value and this helps in identifying the compound that moves across the chromagraphic paper. Every amino acid has its specific Rf value depending on the specific solvent and concentration of solvent used. Based on their affinity towards the stationary phase or the mobile phase on the chromatography, amino acids have different Rf value. There are many properties based on which Rf values are given like hydrophobicity, hydrophilicity, polar, non-polar etc. Since the given amino acid is not present based on the Rf, it can be either of the 15 but without knowing the Rf value, it is difficult to determine which amino acid it is that is present in the unknown sample
