Chirality center meaning
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. WebWhat are chiral centers? A chiral centre is an atom that has four different groups bonded to it in such a manner that it has a nonsuperimposable mirror image. The term "chiral …
