Pay attention to absolute stereochemistry.How many hydrogens are implied at the indicated carbons?Draw a diastereomer for each of the following compounds: Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Show the appropriate stereochemistry by choosing the dashed or wedged buttons and then clicking a bond on the canvas.
- Below are two potential methods for preparing the same ether (Option A and B), but only one of them is actually successful. Identify the successful approach (A or B)Provide the IUPAC name of the compound shown below please don’t forget to include the stereocenters.Consider the E2 elimination of 3‑bromopentane with hydroxide. The starting material consists of a chiral carbon with an in plane bond to bromine pointing to the upper left, an in plane bond to ethyl pointing to the right, a wedged bond to ethyl pointing to the lower left and a dashed bond to hydrogen pointing to the lower left. This reacts with hydroxide to form the product, water and bromide ion. Complete the curved arrow electron-pushing. Use three curved arrows to show the conversion to the product. Draw the organic product.
