Lecture 9 EAS 2 In Class Assignment Name: 1. Draw the complete mechanism of nitration and...
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).
a) Complete the generic mechanism for an electrophilic aromatic
substitution (EAS) reaction using El as the electrophile and show
how the sigma complex is resonance stabilized. Use curved arrows to
show the mechanism and the conversion between resonance structures.
Make sure to add any missing charges. Note the use of a generic
base in the last step. b) Label the reaction coordinate diagram for
a typical EAS reaction shown below by correctly placing the letter
for each structure on the...
Draw the SN2 mechanism of the reaction between (S)-2-bromobutane
and iodid ion. Show lone pairs, electron pushing arrows, 3-D view
to reflect appropriate stereochemistry, reactants, transition
states, and products. name the product. draw and completely label a
reaction energy diagram corresponding to the mechanism you have
drawn.
f. Draw the Sn2 mechanism of the reaction between (s)-2-bromobutane and iodide ion. Show lone pairs, electron pushing arrows, 3-D view to reflect appropriate stereochemistry, reactants, transition states, and products. Name the product....

The following is not part of the lecture-preparation assignment. They will be discussed in class instead. However, you are strongly encouraged to try them before coming to class so that you will get the best result from the discussion. Print this out and bring to class. 1.
