Draw the structure(s) of the major organic product(s) of the following reaction. 1. lithium diisopropylamide/ hexane Br 2.1 eq. You do not have to consider stereochemistry. • Omit products derived from the acidic or basic reagent itself, e.g. HN(i-Pr)2 derived from N(i-Pr)₂. If no reaction occurs, draw the organic starting material. If substantial starting material is present at the end of the reaction, include it in the products. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. 85 ? ChemDoodle n [F 8c

Part B involves the addition of sodium acetate in the reaction between 2.6- and chloroacetyl chloride. Why is sodium acetate used in this step? dimethylaniline To quench the side product (HCI) so that it can not protonate aniline. The protonated aniline is a stronger nucleophile so less reactive To quench the side product (HCI) so that it can not protonate aniline. The protonated aniline is a weaker nucleophile so less reactive O To quench the side product (HCI) so that it can not protonate aniline. The protonated aniline is a stronger nucleophile so more reactive O To quench the side product (HCI) so that it can not protonate aniline. The protonated aniline is a weaker nucleophile so more reactive

Rank reactivity of Sn2 reactions with sodium iodine and explain why. 1-chlorobutane, bromocyclobutane, 1-bromo-3-phenylpropane, benzylbromide.

Please give the principal organic product of each reaction, please specify stereochemistry if it applies. You don't need to assign the stereochemical notation of the product. You should use correct structure drawing to show the stereochemistry.
