Azo Dye of N OH gist Nucleophile Electrophile

e 2. Draw the structures and explain why CH3CH₂O and CH3CO₂ are good nucleophiles but CH3SO3, water, and alcohols (R-OH) are poor nucleophiles. Propose a 'cutoff for the amount of negative charge needed to be a good nucleophile. CH3CH₂O CH3CO₂ CH3SO3 H₂O CH3OH

Please draw out the whole mechanism for the following reaction.

Complete the mechanism for the resonance stabilization. Draw the curved arrows, and complete the structure of the second resonance form.

Determine which would be more reactive with a nucleophile

Create a synthesis starting with the right side as the reagent and the left side as the product

a) Draw a detailed mechanism for the reaction and show the structures of the endo and exo products.b) Label the endo and exo product in part a. c) Which transition state is lower in energy, the one leading to the exo product or the one leading to the endo product? d) Which product do you expect to be more stable (the exo or the endo product) and why? Using your answers to part c and d, draw the reaction co-ordinate diagram for the Diels-Alder reaction shown above. Which product do you expect to be favored at high temperatures, and which product at low temperatures (which product is the kinetic product and which one the thermodynamic product)?

From each pair, select the stronger nucleophile. Q.) CH3COO- or OH-
