Organic Chemistry 1 Here is the professor's solution to the problem. However, I do NOT understand the solution. Please explain the answer in a clear step-by-step fashion to me. Explain the answer provided in the image in a clear fashion and as if I did not know much about organic chemistry. It seems to me like the professor is making the problem more complicated than it has to be. Can you demystify or simplify this problem about D glucose? How can you assign priorities on a Fischer projection? I don't get it.
