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. WebA test for achirality is the presence of a mirror plane within the molecule. If a molecule has a plane within it that will cut it into two symmetrical halves, then it is achiral. Therefore, lack of such a plane indicates a molecule is chiral. Compounds that contain a single stereo-center are always chiral.
