##### Draw the Fischer projection for the D-2-ketotetrose.

Draw the Fischer projection for the D-2-ketotetrose. Switch between an aldose and a ketose by clicking on "switch carbonyl group." Add or delete carbon atoms using the add (" +") or delete ("x") buttons. Clicking on a blue box once adds a hydrogen atom (H). Clicking on a blue box again toggles between H and OH.

##### The Gabriel synthesis transforms an alkyl halide into a primary amine via a two-step process.

The Gabriel synthesis transforms an alkyl halide into a primary amine via a two-step process. Follow the directions below to draw the initial mechanism and final products. Draw curved arrows to the next step. Draw the missing nonbonding electrons, charge and curved arrows. The first three steps are correct. I am unsure about how to complete the final step.

##### Draw the structures of the organic products in each reaction of the following two-step synthesis.

Draw the structures of the organic products in each reaction of the following two-step synthesis. (Hint: The nucleophilic amine attacks the electrophilic carbonyl carbon, and the resulting intermediate undergoes a proton shift and dehydration. Recall what is eliminated in a dehydration process. The second step is a reduction reaction; the reducing agent is NaBH3CN (or H2, metal catalyst). The aromatic ring is unaffected by these reagents. Look at the product of the first reaction and consider what can be easily reduced.)
