You continue to impress people at the chemical company and they give you a special assignment. Compound C needs to be converted to Compound D and you are tasked to come up with a route for this. Design a route to take C to D, outlining the reagents you would use for each step. You should use only reactions that have been covered in the CHEM 2443 course, and it will take more than one step. с ?? یڈ۔ Br Br D
