Someone please help me with this problem
Enantiomers have very similar physical properties,
while for diastereomers they can be very different. This fact is
important in the separation or resolution of enantiomers. In the
lecture, we looked at how chiral chromatography is used to separate
enantiomers: first, by reacting them with an optically pure chiral
reagent (i.e., pure R or S) to form a pair of diastereomers, then
separating them using chiral chromatography, and finally detaching
the chiral reagent to...

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...
