When you look at it that way, they're clearly different, and should be treated as such. – wes3449. WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.

WebThe orientation of chiral centers can help differentiate between various stereoisomers. These centers can be described as R or S, meaning the molecule can have either “right-handedness” or “left-handedness”. Label the groups by priority 1-4, with the highest priority being 1. If two atoms are the same, look to the next connected atom. Web20 de out. de 2024 · The stereochemical labels R and S are assigned thus: in the direction of an arrow pointing from the highest priority atom (labelled 1) to its highest priority neighbour (labelled 2), interlocked rings that are disposed in a clockwise manner are R, those in an anticlockwise manner are S.
