1. NaOEt CO2Et 2. H30+ 3. heat Br. Br CORET + H3C V CO2H H₂C + CO2 + E H3C CO2Et The malonic ester synthesis is a carbonyl alkylation reaction. It is used to prepare carboxylic acids from primary alkyl halides, lengthening the carbon In progress by two atoms. Thus, the product can be visualized as being a "substituted acetic acid." The reaction consists of three steps: generation of the enolate anion followed by SN 2 reaction with a primary...

Answer the following parts
Part A. Once you have obtained the electrostatic potential value
for your unknown acid, use the plot you obtained for the known
carboxylic acids to obtain the pK, value for your unknown acid. Do
not "eyeball" the pK, value on the graph. Rather, using your
trendline to calculate the value will be a more accurate
determination. Show your calculation in the space below
Part B. (4) Using a reputable source, report the pKa literature
value for...

of the following acids, which one would be least likely to
donate urs proton due to the unstable conjugate base?
1. which is the donatable hydrogen for each of the given
structures?
2. what is the hybridization of the atom to which the
donatable hydrogen is attached?
3. do any of the atoms identified in question 2 have a
positive charge? if so explain why this is not a good thing and
makes the hydrogen more donatable as opposed to...
