NHCH3 NaOH, H₂O a. Draw the structure of the tetrahedral intermediate INITIALLY-FORMED in the reaction shown. You do not have to consider stereochemistry. • Do not include counter-ions, e.g., Na+, I, in your answer. • In cases where there is more than one answer, just draw one. **ELL ChemDoodleⓇ b. Draw the structures of the organic products of the acyl transfer reaction. You do not have to consider stereochemistry. • Draw the neutral form of the products; no charges. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate multiple products using the + sign from the drop-down menu.

Draw the structure of the tetrahedral intermediate initially formed and draw the structures of the organic products of the acyl transfer reaction.

For the SN2 reaction, draw the major organic product and select the correct (R) or (S) designation around the stereocenter carbon in the organic substrate and organic product. Include wedge-and-dash bonds and draw hydrogen on a stereocenter. Br. CEN Η G 2 Select Draw Templates More C H N 2 Q Erase

Consider this organic reaction: Br Draw the major products of the reaction in the drawing area below. If there won't be any major products, because this reaction won't happen at a significant rate, check the box under the drawing area instead. No Reaction.
