1) Please explain what it means for a reaction to create a Markovnikov product. Why does the reagent favor being added in this order and not Anti-Markovnikov See the reaction below. 2) Why do molecules perform carbocation rearrangements? How will you determine when to perform a carbocation rearrangement? see reaction below. The X-
Draw curved arrows to show the movement of electrons in this step of the mechanism.
Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry. The electrophilic H+ adds to the sp2 carbon with the most hydrogens to yield the most stable carbocation intermediate, which then adds water to give the product alcohol. Because a carbocation intermediate is formed, rearrangements can occur prior to the addition of water. To avoid the possibility of rearrangement and still give a Markovnikov alcohol, alkenes can instead be treated with mercury(II) acetate in aqueous THF and then subsequently...

Draw the mechanism and expected product for hydrohalogenation of the folowing alkene with HBr. Draw the mechanism and expected product upon Markovnikov hydrohalogenation with HBr of the alkene shown below. Draw the major product for the following reaction The expected major product(s) of HBr addition to the alkene shown would be: Draw the reaction intermediate formed when 4-methylcyclohexene reacts with Br_2

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...

Consider the reaction below. Understanding what you know about resonance stabilities provides the 2 possible carbocations and the resonance structures of H+ addition to the reactant. Circle the carbocation that is the major product due to resonance stabilities. Provide the 1, 2 and 1, 4 products of that carbocation: Why did you pick that carbocation? Provide the 2 unlikely products of 1, 2 and 1, 4 additions from the other carbocation intermediate not chosen above. Hopefully you noted that the...
