Organic Chemistry I Homework Worksheet Alkenes: Three Hydration Methods Compare and contrast the three alkene hydration methods: acid catalyzed hydration, oxymercuration-demercuration, and hydroboration-oxidation. Make sure to include each mechanism and how it affects regio-and stereochemistry. Give examples!! Label everything!!!
questions 6, 7, and 8 please! :) ochem
6. The alcohol below can be made from two different alkenes via a hydroboration/oxidation series, but one of the potential alkene starting materials isn't good because it produces 3 other isomers in addition to the compound below. Draw all 3 and indicate their relationship to the product below (i.e., enantiomers, diastereomers, etc.). OH 7. What is the product when cholesterol is subjected to hydroboration/oxidation conditions? 8. The compound below reacts differently under...
Acid Catalyzed Hydration-treatment of alkenes with water in the presence of acid catalyst leads to the formation of alcohols. H2SO4/H2O > 150°C Mechanism Major Product Acid catalyzed dehydration goes through a carbocation intermediate. This means that the Markovnikov product is obtained when carbocation rearrangements do not occur. The need for excessively high temperatures makes this reaction of limited use in laboratory synthesis. Oxymercuration - Oxymercuration involves the addition of Hg to the alkene using mercury (II) acetate Hg(OAc) followed by...
Alkenes can be converted to alcohols by hydroboration-oxidation.

characterized as being
_____ R,R

Please help with the question that I have circled in red. This
is from a lab I did and I have included the entire handout in case
it helps you to answer the question.
2015 Chem 263 2-Credit Org Lab 6T: Dehydration of Cyclohexanol to Cyclohexene Lab 6T w lecture you recently learned that alkenes undergo acid-catalyzed addition of H20 (hydration of the alkene) to yield alcohols. This lab with illustrate the same chemistry in reverse; the microscopic reverse of...
