How many enantiomers and diastereomers are possible. Assign (R) and (S) configurations for all the structures. What are diastereomers? 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.

Alright guys in this video I kind of want to have the final word on Chirality because it turns out that there's one assumption we've been making that isn't totally correct which is that a Chiral center is always going to be a carbon, it turns out guys that there is a such thing as non-carbon chiral centers and that's what we're ... WebChirality centers must be sp 3 hybridized, meaning that a chirality center can only have single bonds. In organic chemistry, a chirality center usually refers to a carbon, phosphorus, or sulfur atom, though it is also possible for other atoms to be chirality centers, especially in areas of organometallic and inorganic chemistry.

WebTo determine whether the chirality center is R or S you have to first prioritize all four groups connected to the chirality center.
