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-

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...

An irreversible reaction A + B products is studied under conditions where the initial concentrations of A and B are equal. Under these circumstances, a graph of ln([A]) as a function of time is linear. What is the order in A? (A) Zeroth order B) First order (C) Second order (D) The order in A cannot be determined based on the information given. Doesn't the first order reaction kinetics say that the graph of ln[A] vs t gives a...
