- 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.Organic Chemistry 1 Here is the professor's solution to the problem. However, I do NOT understand the solution.

- The LD50 (“Lethal Dose, 50 %”) is a value used in toxicology which gives the amount of a substance required to kill 50 % of a test population. It is usually reported based on body weight. For racemic carvone LD50 is reported as 1640 mg/kg. 1. Would it consider carvone to be toxic to an average person? Explain. 2. Would it be expected this the LD50 value to be the same for each enantiomer? Explain at the molecular level in stereochemical terms.1. draw the most stable chair form of (1R,2R)-1-ethyl-2-methylcyclohexane 2. in the following chiral compound, the stereogenic center is denoted by C*. assign the priorities to the groups attached to C* using the Cahn-Ingold-Prelog system. please show your work (the image goes with question 2)Build 2‑bromoethan‑1‑ol and its mirror image. 2‑Bromoethan‑1‑ol, which has condensed structural formula BrCH2CH2OH, is also called 2‑bromoethanol. a.
