So I have been trying to understand how to draw R and S configurations. I feel like I have understood how to draw them, but every time I do a question, I get a wrong answer.

So here is what I have understood,

  1. The lowest priority goes to the back of the compound meaning on the dash line.

  2. The highest priority is on the top.

    The highest priority is on the top.
  3. You can play around with the 3rd and 4rth, so that one is on the 'out of page' and the other is on the line, so that you can differentiate between the R and S.

I have been going crazy trying to understand it. The things I do not understand are these,

  1. I understand the diagrams on the right side. That I have been doing as well

  2. But then when we look at the diagrams on the left. The configuration is completely opposite. Even though it says S, the configuration is like of a R. Plus the highest one is going into the page and not the hydrogen. WHY? It is driving me crazy because they do that for all the examples. When they S, they actually make an R and vice versa. Whereas on the internet it is a different story. So I really need someone to tell me what I should do.
