1. Describe and write necessary equations describing generation of electrophile for nitration.
Describe and write necessary equations describing generation of the electrophile for nitration and at what step of the experiment the electrophile is generated.
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

For each of the salts, write a chemical equation describing their acidic/basic behavior in solution. For any salts that are neutral, describe why they are neutral. For any salts with amphoteric ions, write equations for both processes and indicate which process predominates. NaCl, NaC2H3O2, NH4Cl, ZnCl2, Na3PO4, Na2HPO4, NaH2PO4

Requirement: (1) Draw necessary free body diagrams, (2) write necessary equations, and (3) name the adopted principle 3. The mass of block is 10 kg and the horizontal force applied to the block as shown in Figure below is 100 N. The coefficients of kinetic friction between the block and the inclined plane is μ A 0.2. Determine the acceleration of the block and its direction. Draw free body diagram and write the needed equation (25 points) 30P
1. Draw the complete mechanism of the first nitration of m-dichlorobenzene, using NO2 + as the electrophile. Remember that this reaction is in extremely acidic conditions, and likely the strongest nucleophile (or BL base) around is water (HSO4 - and NO3 - are also around, but they are less basic than water).
