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...

Acid/Base Extraction
1. Provide a flow chart detailing the acid/base
extraction/separation of the compounds shown below. Your answer
must employ the following reagents: methylene chloride,
hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M),
10% sodium bicarbonate (aq). Clearly indicate the product(s) and
layers formed following each step of your separation scheme.
IMPORTANT: p-cresol is soluble in sodium hydroxide solution but
insoluble in neutral water or sodium bicarbonate solution. 2-

4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...

For each combination of reagents, write a balanced molecular equation. Indicate whether a reaction occurred in each case. If no reaction occurred, indicate "NR" for 'no reaction.' For reactions that did occur, write the net ionic equation for each. Classify each reaction that occurred as acid/base, redox, or a precipitation reaction. CuSO4 and NaNO3 aq (NR) CuSO4 and NaCl aq (NR) Na3PO4 and Pb(OAc)2 aq (rxn) Na2CO3 and CaCl2 aq (rxn) Na2CO3 and HCl aq (NR) HCl and NaOH (aq)...
