Post Lab Questions for Nitration of Acetanilide, Nitration of Methyl Benzoate, Nitration of Phenylacetonitrile, Nitration of Phenol. 1. What product(s) do you expect to be formed in the nitration of phenol? Why? 2. All three of the nitrophenols have boiling points well above 200°C. Explain clearly why it was possible to distill something with such a high boiling point when the temperature of the distillate never rose much above 100°C. 3. What product did you actually obtain in the distillate?...

This question is for the Nitration of Methyl Benzoate, the final
product is Methyl 3 nitrobenzoate but I dont know how to get the
byproduct produced during this reaction. Please use the expanded
structural formulas and show a mechansim on how that occurs and on
the right please provide a description of what is going on in that
step/mechanism, ie an Sn1 or E1, etc.
b. As stated in the Lab Manual for this experiment, a by-product is possibly produced...

Consider the resonance structures of acetanilide and methyl
benzoate provided above.
How does the -COOCH3 substituent on methyl benzoate direct?
Do the partial charges shown on either acetanilide or
methyl-benzoate activate or deactivate the electrophilic
substitution reaction?
Is there a correlation between directing and activating groups?
Explain.
