The expectations should be determined when the TLC plate is allowed to remain the chamber of development for long time, so that the solvent reaches at the top of the plate during analysis of mixture. Concept introduction: TLC works on the principle of separation of constituents of a mixture of compounds based on polarity. The polar compounds interact with the stationary phase thus can move to smaller distance from the base. While the non polar compounds tend to move faster as they interact less with the silica gel; therefore, they move far from the base of the plate.

Question

Please draw the inverted chair forms of the products for the two equilibrium reactions shown below. Circle the equilibrium reaction that would have a AG = 0, i.e., the relative energy of the reactant (to the left of the equilibrium arrows) equals the relative energy of the product? [No requirement to show or do calculations.] CH3 CH3 HH CH3 1 -CH3
