3. Complete the following scheme by showing the key hydrogen atoms (protons) and using curved arrows to clearly show electron movements in all mechanistic steps. B OH

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 MgBr Will the first product that forms in this reaction create a new CC bond? 1。 MgBr 00 Yes ○ No ? Will the first product that forms in this reaction create a new CC bond? ○ Yes ○ No. Click and drag to start drawing a structure. ✗ ח' :
