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).

5. Molecules with an-OH group directly bonded to a C-C sp hybridized carbon are called "enol"'s. The types of chemical reactions which enols undergo are substantially different from those of normal alcohols. By considering the Brensted-Lowry and Lewis acid/base reactivity of an enol, you can predict a few of these differences. (a) Ethenol, the simplest "enol", can react as a BL. base in three different places, by gaining a proton at either of the two...

Draw the different geometric isomers for dibenzalacetone (there are
3 of them). Why is the trans isomer formed in this experiment?
The purpose of this experiment is to svnthesize dibenzalacetone (trans, trans-1. 5-diphenvl-1.4 pentadien-3-one) through the Aldol condensation of acetone with benzaldehyde. The synthesis begins bv using a strong base to generate the acetone enolate ion. Water (not shown) is formed as a byproduct. The equilibrium position of this reaction strongly favors the starting acetone, and the amount of acetone...

How would you track the progress of your reactions and confirm product identification? 2) Create a chart comparing E1, E2, SN1 and SN2 reactions. Be detailed and cover: structure of RX, reactivity of nucleophile, concentration of nucleophile, solvent and stereochemistry. 3) Mixing cyclohexanol with phosphoric acid is an exothermic process, whereas the production of...
