Write a mechanism for the nitration of methyl benzoate (major product only) Include formation of the electrophile from the reaction of nitric acid with sulfuric acid. Only one resonance structure is needed for the intermediate in the EAS portion of the mechanism
Nitration of Methylbenzoate. Lab 1 6. Why is it important to maintain the reaction temperature low and the addition of nitric acid-sulfuric acid mixture carried out slowly? 8. Which ring of phenyl benzoate would you expect to undergo nitration more easily? Explain. 9. Which is nitrated faster, toluene or phenol? Explain. phenol or nitrobenzene methyl benzoate or phenol nitrobenzene or methyl benzoate benzene or toluene 10. Show all mono, di and trinitration products of toluene. Do you think the mononitration...
Nitrobenzene is made by the direct nitration of benzene by nitric acid in the presence of strong sulphuric acid solution: CHe+HNOCH,NO2+H2O The actual nitrating agent is the nitronium ion, NO27, and the sulphuric acid is needed to generate this from the nitric acid feed Reconcentrated sulphuric acid, of strength 74% by weight and XC is mixed with pure nitric acid at 25°C to give a nitric acid strength in the mixture of 7.5% by weight. The heat of mixing causes...

Provide the reaction for chlorination of benzene using electrophilic aromatic substitution, it's complete mechanism including formation of "super" electrophile, and a completely labeled reaction coordinate energy diagram. 1.
1. Write the mechanism for the synthesis reaction for Nitration of Methyl Benzoate C₆H₅CO₂CH₃ + HONO₂ --------> C8H7NO4 H₂ O Methylbenzoate + Nitric Acid (H₂ SO4 ) Methyl m-nitrobenzoate water Write the complete mechanism for the reaction. Be sure to use expanded structural formulas for all chemical species. Include all bonds, non-bonding electrons, formal charges, and electron-flow arrows. DO NOT use bond-line formulas, but rather explicitly show atomic symbols. For this mechanism, show the individual resonance contributors for the arenium...
The mixture of dimethylsulfoxide (DMSO) and hydrobromic acid
results in the formation of bromodimethylsulfonium bromide, which
can serves as a source of electrophilic bromine.
Draw the complete mechanism to generate the major product. Your
mechanism should include: generation of the active halogenating
species and the steps to provide the stable product, proper arrows,
formal charges, and labels for the rate-determining step. You
should also draw all important resonance structures for any
reaction intermediate(s).
