1. Explain why the elimination reaction in acetone promotes an E2 mechanism while water promotes and E1 mechanism?
2. Which product is more thermodynamically stable, the E or Z isomer?
3. How can you use NMR spectroscopy to differentiate between the E and Z products and also determine their relative ratio?
4. When the solvent for the reaction is acetone, the procedure recommends that the acetone be removed prior to the extractions, why is this important?
5. In the extraction procedure, which layer do you expect to be the organic layer, and which layer do you expect to be the aqueous layer? what physical property do you need to know in order to predict this?
What is the percentage yield of SO3 if 22.3 g SO3 are obtained from the reaction of 25.0 g SO2 with an excess of O2.
Determine the molarity of a solution of sodium hydroxide (NaOH) if 27.9 mL of this solution combines exactly with 22.30 mL of 0.253 M
Clearly indicate coordinate system used in finding the answer. Basically trying to work up to building the molecular orbital diagram. I am stuck in the step where you determine the transformation sequences of each symmetry subset.
