3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...

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...
