Consider the following sets of problems:
I was hoping someone could clarify what each checkbox means exactly. All of these answers are incorrect (except the first one with the check marks signifies the correct answers).
For example, why are the first pair different molecules? What makes something a conformation/constitution/structural isomer?
What does it mean to say something is an "identical conformation of the same molecule" vs "different conformation of the same molecule?"
When can I definitiviely tell if something is an enantiomer or just a diastereomer? It seems like (for an enantiomer) you can't just do the check of "switch all dashes to wedges and all wedges to dashes" because, as in the third pair of newman projections, they are enantiomers of each other but I don't understand why that is.
