Alkenes can be converted into alcohols by acid-catalyzed
addition of water.
Assuming that Markovnikov’s rule is valid, predict the major
alcohol product from 3-methylenepentane.
Do not consider stereochemistry. Remember to consider hydride and
alkyl shifts.

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.

Alkenes can be converted to alcohols by reaction with mercuric acetate to form a B-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces the C-Hg bond to a C-H bond, forming the alkyl alcohol, a reaction called demercuration. Draw the structures of the Hg-containing compound(s) and the final alcohol product(s) formed in the following reaction sequence, omitting byproducts. If applicable, draw hydrogen at a chirality center and indicate stereochemistry via wedge-and-dash bonds. Draw 2 Neutral product(s) of...

Acid Catalyzed Hydration-treatment of alkenes with water in the presence of acid catalyst leads to the formation of alcohols. H2SO4/H20 > 150 °C Major Product Mechanism Acid catalyzed dehydration goes through a carbocation intermediate. This means that the Markovnikov product is obtained when carbocation rearrangements do not occur.
