Column chromatography was performed on a mixture containing compounds A, B and C using silica gel as a stationary phase and a 50:50 mixture of ethyl acetate:petroleum ether as the mobile phase. Six individual fractions were collected during the separation, and TLC analysis of the fractions provided the data shown. Evaluate and explain whether this column was successful in separating compounds A, B and C. If the column was not successful, suggest what changes could be made to provide a successful separation of this mixture. 1 2 3 4 5 6
