1. Take your original model or molview image (from Step A), and turn it around (or use the cursor to turn the molecule) to get everything aligned with your Step C (first exchange) drawing as much as possible (it may or may not align perfectly, but align as many of the atoms as possible).

How does the post-exchange molecule (Step C) compare with the pre-exchange molecule (the original model)? Choose ONLY one of the following answers: exactly identical to each other; stereoisomers; constitutional isomers; or completely unrelated.
