When assigning configurations to wedge and dash structures, they are simple because I can clearly see which atoms are in the front/back of the plane.
However, when given structures like these, which are more of a 3D field, I have trouble assigning the configuration.
There are 3 chiral centres here, and I have determined one to be S and the other to be R.
However, for the C marked with "*", I believe that it should be S because the ranking of the atoms are in anti-clockwise fashion (as seen in red).
There is another H connected to the C, which isn't drawn so I assume it's pointing downwards.
However, the answer given is R instead. Why is that so? Is the H atom not directed downwards for 3D structures like these?
