1 pt 1 pt The final step in the hydration of an alkyne under acidic conditions is the automerization of an enol intermediate to give the corresponding ketone. The mechanism involves a protonation followed by deprotonation Consider the following tautomerization reaction: CH2 CHE H,09 1 pt 1 pt 1 pt OH 1 pt 1pl For the mechanism step below, draw curved arrows to show electron reorganization Where relevant, a pi bond has two hot spots when you draw a curved...

Fill in the boxes over each arrow with the letter that
corresponds to the reagents needed to perform each step of the
multistep synthesis show below. Reagents may be used more than
once, or not at all. Pay close attention to the numbered carbons in
the starting material, and be sure that your answer accounts for
the position of these carbons in the final product.

Can you help me identify reagent (i), Compound 8 and
Compound 12 in the reaction scheme?
You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
The lab data for Compound 8 and 12 is as
follows:
You can use any...

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
