2020.03.04 21:58 sivoboceze What's the best set of molecular models for graduate-level organic chemistry?
As a result of my complete and utter inability to draw decalins or any other polycyclic compounds, my professor has recommended that I buy a set (or rather, multiple sets) of molecular models to properly assemble these molecules such that I can actually draw them. So, what's the best molecular modeling kit for my needs? It has to be relatively affordable, because I want to buy multiple sets in order to assemble large models. Any suggestions are quite helpful, though.

Hi everyone,
First off I want to say that I have already tried to tackle this problem using models and so forth, and I think it would be more beneficial for me to learn this without having to depend upon models. With that out of the way, my question is how the hell do I draw the other possible conformation of cis-decalin (after the chair flip)? I know that one ring is equatorial and the other is axial, and the ring flip in the equatorial ring is easy (It's done the same way as any other ring flip) but HOW DO I POSITION THE SECOND RING. This is seriously bothering me.
