WebSep 10, 2024 · Therefore, this is a chiral center, meaning it has two different mirror images: S and R. Since there is only one chiral center, then there are two chiral forms of this molecule: (1S)-1-chloro-1-fluoroethane and (1R)-1-chloro-1-fluoroethane. When only one chiral center exists, you can write it like this simply without parenthesis or numbers ... 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. gorkhe class 12
