Part 9: TLC Methodology (Thin Layer Chromatography) 39 related questions found What is Rf value full form? In thin-layer chromatography, theretention factor(Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided...
saturated NaHCO3 and extracted with Et2O. The combined ethereal solution is washed with saturated NaCl, dried (MgSO4), and concentrated. The residue is purified by silica gel chromatography (EtOAc/petroleum ether 1:20) to obtain the desired product as a colorless oily liquid with a yield of ...
