(R)-2-methylbutan -1- ol (structure shown on the right )is an optically active compound that has a specific rotation value of +5.75° over a sodium D-line wavelength at 20°C. It's racemate (same compound different configuration) (S)-2-methylbutan -1- ol would have the same specific rotation value but of opposite sign. a. What are concentrations of both of these compounds if the pathlength used for the cuvette is 2.3 cm and each would have observed rotation of ± 1.151°? b. To arrive at these two compounds as products, what specific molecule should be your starting reactant? Draw a detailed reaction mechanism outline for the formation of these two compounds.

The specific angle of rotation of (R)-2-bromobutane is -23.1°. Treatment of (R)-2-bromobutane with potassium bromide produces a racemic mixture of (R)- and (S)-2-bromobutane, which is optically inactive. The rate at which the product's angle of rotation decreases is directly proportional to the concentration of KBr. Does this suggest that the reaction takes place by an SN1 or an SŅ2 mechanism? Explain.
