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. WebHowever, the only criterion for chirality is the nonsuperimposable nature of the object. A test for achirality is the presence of a mirror plane within the molecule. If a molecule has …
