H2SO4 + ОН HO a. A strong acid is used to catalyze this Fischer Esterification of acetic acid. What two steps in this reaction are accelerated by the presence of strong acid, and what function does the acid play in each of these steps?

potassium dichromate (Cr2O7^2-) oxidation of ethanol to acetic acid is the basis for the original breath-alcohol screening test used by law enforcement agencies to determine a person's blood alcohol content (BAC). the test is based on the difference in colour between the dichromate ion( redish orange) in the reagent and the chromium(iii) ion (green) in the product. deduce the reaction that is involved in this test and give the IUPAC name of the other product formed.

One of the steps in fat metabolism is the hydration of crotonate to yield 3-hydroxybutyrate. This reaction occurs by addition of —OH to the Si face at C3, followed by protonation at C2, also from the Si face. Draw the product of the reaction, showing the stereochemistry of each step.

Sodium borohydride (NABH4) is said to be a chemoselective reducing agent. Which of the following best describes what this term means? O 1 A reaction that operates exclusively on one functional group in the presence of other functional groups. A reaction that operates on one functional group at a time and is shut down 2) when other functional groups are present. O 3) A reaction that does not operate at all in the presence of a functional group. OA reaction that operates on multiple functional groups in the presence of 4) multiple functional groups.
