WebStereogenic Center – Origin of Chirality. Next, we need to discuss what makes molecules chiral, or, which is to say their mirror images are not superimposable with the original structure. Although, there are different types of chiralities, most often, the origin of chirality in organic molecules is the presence of an asymmetric carbon. Notice ... 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.

WebThis organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. ... WebAbout this unit. Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections.
