Please help with pre-lab questions.
Pre-Lab Questions: 1. A sample of 2-butanol has a specific rotation of +3.25. Determine the optical purity (%ee) and percent composition of this sample (see Mohrig section 17.4). The specific rotation of pure (+)-2-butanol is +13.0°. 2. The equation for the formation of the diastereomeric salts is shown in the background information (performed in Part A of the procedure). Write this chemical equation in your notebook, then ALSO write a balanced equation for the formation...
