b Write a mechanism for the reaction using curved arrows to show electron reorganization. Consult the arrow-pushing instructions for the convention on regiospecific electrophilic attack on a double bond. Arrow-pushing Instructions inox tv no H- B Draw the organic product of the following reaction. CH3 meta-Chloroperoxy- benzoic acid • You do not have to consider stereochemistry. • Indicate regiochemistry when relevant. • The aromatic ring, when present, is unreactive in all cases. • Do not draw organic or inorganic by-products....

Michael (conjugate) addition reaction."
I suck at mechanisms :( help would be much appreciated, thank
you!

What reaction conditions are required for the alkane > alkyl halide conversion? b. Assuming that X- CI, propose a complete mechanism for the entire reaction c. Assuming that X Br, propose a complete mechanism for the entire reaction d. Which of the above mechanisms would produce the highest...
Notes: A ‘detailed’ mechanism should illustrate all intermediates, by-products, and electron-pushing arrows. The marking scheme is given for each question as a guide; It is subject to minor changes. In class, we learned how to synthesize epoxides from alkenes using meta-chloroperbenzoic acid (mCPBA). Epoxides, like bromonium ions and mercuronium ions, can be ring-opened with various nucleophiles. The stereochemistry of the product depends on if the ring-opening occurs under acidic or basic conditions. The following two reactions – ring opening of...
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...
