propose a mechanism--not the name of the mechanism, but showing electron movement-for following reaction. Your mechanism must account for both products and show intermediates

b) Provide a detailed mechanism (with arrows) and show all relevant reaction intermediates for the following azo coupling reaction. -ZEZ Br NO CIO N Br 'N-

3) Any compound or ion with at least one lone pair can be considered a base and/or a nucleophile. The relative basicity and nucleophilicity of the species is one of the most important factors that determine the mechanism of a reaction on sp³-carbon atoms. Please show an example of a) a reagent that is a strong nucleophile and a strong base, b) a reagent that is a weak nucleophile and a strong base, c) a reagent that is a strong nucleophile and a weak base, d) a reagent that is a weak nucleophile and a weak base. Which nitrogen atom in the structure below is most nucleophilic? Please explain by discussing the electron density around each nitrogen atom. Show at least three resonance structures of the compound. N.

Substitution and elimination: predict the product Maximum allowed tries per question: Unlimited (7) Draw the major organic product of the reaction. Follow this procedure: determine whether the reaction conditions are acidic or basic; identify the most nucleophilic/basic atom, the electrophilic atom, and the leaving group; predict whether elimination or substitution will occur; and then draw the product. Indicate the stereochemistry at every stereocenter with a single wedged (up), hashed (down), or wavy (a mixture of up and down; either) bond.
