Consider the reaction of two compounds 'A' and 'B' which could make two possible diastereomers 'AB' and 'BA' (much like this week's Diels Alder reaction). Reaction pathway 1: A + B → AB E, = 12.0 kJ/mol AG = -30.0 kJ/mol Reaction pathway 2: A + B – BA E = 13.0 kJ/mol AG=-21.7 kJ/mol a a) Which of the two products (A or B) will form in greater abundance under thermoydynamic control? Which will form in greater abundance under kinetic control? Explain your responses using a sketch of the reaction coordinate diagram for the reactions described above. b) Assuming kinetic reaction control, how much more of the kinetically favored product will form (as a percentage of the total product) when the reaction is run to completion at 275 K? Show your calculation. c) Assuming thermodynamic reaction control, how much more of the thermodynamically favored product will form (as a percentage of the total product) when the reaction is run to completion at 450K? Show your calculation.
