Fischer and newman projections
WebWhy are there different Newman projections for one molecule in organic chemistry? Since one can rotate the C-C bonds about each other we can have a number of conformations. CaH 3 − CbH 2 − CcH 3 where a,b,c … Just like when converting the Newman projection to bond-line structures, you need to decide a viewer direction. Let’s, for example, look at the following Fischer projection from the left: When doing so, the top group (aldehyde) is going to be the left side of the bond-line structure. Keep in mind that the … See more First, remember that a given molecule, and even a specific conformation of that molecule, can have many Newman projections … See more In order to convert a Newman projection to the corresponding bond-line structure, you need to look at it from the side. So, first, decide the … See more Aside from these strategies for converting between different representations of organic molecules, there is more good news if you still don’t quite like those!
