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.

Synthesis of dimedone This lab exercise will give you practical experience with the generation of a malonic ester enolate and subsequent reaction with an a,p-unsaturated carbonyl compound. This sequence is known as the Michael reaction. In the presence of sodium methoxide, dimethyl propanedioate (malonic ester/dimethyl malonate) is converted to the corresponding enolate anion and reaction with 4-methylpent-3-en-2-one (mesityl oxide) affords the Michael adduct 1, as shown in the reaction sequence below. Under the basic reaction conditions, the Michael adduct 1...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
