Enantiomers have the same physical properties and cannot be separated using typical laboratory methods. One method of separating a racemic mixture is to use chiral column chromatography. Select the true statements below. There are 2 true statements. 1. the column converts one of the enantiomers to the other 2.a chiral solvent is used in chiral chromatography 3.a chiral absorbant is used in chiral chromatography 4.one enantiomer will elute faster than the other

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...

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...
