Question

Write all the acid-base reactions taking place in this experiment, including the full structure of all compounds involved. Include approximate pK_ a's and show which direction the equilibrium is favored. Which of the following amines could in principle be used as a resolving agent for a racemic carboxylic acid? Given the specific rotation of the R-enantiomer of the following alkene and its molecular mass, answer the following questions. What is the observed rotation of a 0.5 solution of this compound in a 5 cm sample path? What is the observed rotation of a solution formed by mixing equal volumes of the solution from part a and a 0.25 M solution of the enantiomer of the same alkene? Which of the salts below should have identical solubilities in methanol?

Explanation / Answer

3Q.

IMPORTANT POINTS TO BE NOTED

1. AMINE USED AS A REAGENT TO RESOLVE RACEMIC CARBOXYLIC ACID MIXTURE HAS TO BE CHIRAL

2. BOTH +/- AMINE CAN BE USED FOR SELECTIVE REMOVAL OF CARBOXYLIC ACID

THEREFORE BOTH +/- Ph-CH -(CH3)-(NH2)-CH3 CAN BE USED
