Draw the structure of the product obtained when this amine is treated with excess iodomethane and then heated with Ag₂O (Hoffman elimination). ball & stick labels • Consider E/Z stereochemistry of alkenes. • Draw only the elimination product, do not the leaving group. • In cases where there is more than one answer, just draw one.

↑ k 个 G Draw the major product from this reaction. Use wedge and dash bonds to indicate relative stereochemistry where appropriate. Ignore acid byproduct. 1. Br2, H₂O 2. NaOH < Q

Draw the major organic product(s) of the following reaction. CI H₂O + NaOH You do not have to consider stereochemistry. •If no reaction occurs, draw the organic starting material. • When SN1 & E1 pathways compete, show both the substitution and the elimination products. • Separate multiple products using the + sign from the drop-down menu. Do not include counter-ions, e.g., Na+, I, in your answer.

What is the missing reactant in this organic reaction? N amcocon NH₂ + R ام و این بار در + H₂O Specifically, in the drawing area below draw the structure of R. If there is more than one reasonable answer, you can draw any one of them. If there is no reasonable answer, check the No answer box under the drawing area. Note for advanced students: you may assume no products other than those shown above are formed.

Complete the mechanism for the keto-enol tautomerization shown using bonds, charges, nonbonding electron pairs, and curved arrows (forward reaction only). Do not delete any pre-drawn bonds, charges, or lone pairs. If you accidentally delete a vital part of the structure, click the undo button in the lower left. Step 1: keto form. Draw curved arrows. Step 2: complete the structure, then add curved arrows. Select Draw Rings More Erase Select Draw Rings More Erase H H - H :0: :0: :o: 1L :o:

Curved arrows are used to illustrate the flow of electrons. Using the provided starting structure, draw the curved electron-pushing arrows for the following reaction or mechanistic step(s). Be sure to account for all bond-breaking and bond-making steps. Then draw the organic product of this initial step. Include all lone pairs in the structures. Ignore inorganic byproducts and counterions. Select to Add Arrows CH3 CH3OH Drawing H I

Draw an alkyl bromide that would produce ONLY the following alkene in an E2 elimination. Ignore any inorganic byproducts.

For the given molecule, highlight any nucleophilic sites in red and any electrophilic sites in blue. ୮

Draw the major product of this reaction. Ignore inorganic byproducts and the alcohol side product
