5B: Even molecules with the same chemical formula can have different shapes even though they may be comprised of the same atoms. For instance, with one sheet of paper, you can make origami swans of so many different shapes - similarly molecules can come in different conformations. We will walk through the concepts of structural and conformational isomers as well as stereoisomers and diastereomers
