Epoxide Ring-Opening Post Lab Question: There was a marked difference in the final product distribution from this weeks acid-catalyzed reaction versus the base-catalyzed reaction. Was one set of reaction conditions more regiospecific than the other? If so, why do you think that this was the case? Explain your reasoning in detail.

seperation of acid neutral
Experiment 5: Separation of Acid-Neutral Mixture Post-Lab Questions 1. Draw and label the structures of the major and minor components of the acidic and neutral mixtures. 2. Although acetic acid - water may be used as a "solvent pair", why are dilute solutions of an inorganic acid/water (or, inorganic base/water) avoided in recrystallization attempts? (Hint: see Wade Ed: Sections 21-12, 21- 13. Consider functional-group possibilities.] 3. Using a flow diagram, show the separation of a mixture...

Please give detailed answers to the pre and post lab questions.
Thank you!
NUCLEOPHILIC DISPLACEMENT- FORMATION OF AN ETHER BY AN SN2 REACTION Bond formation by use of an SN2 reaction is very important for organic and biological synthesis. Many new bonds formed make use of this versatile reaction pathway. In this reaction, one partner is the nucleophile and the other partner is the electrophile. The electrophile will have a leaving group that will be lost in the reaction. In...
