Webchiral A molecule that is not superimposable on its mirror image. Typically a carbon atom bonded to four different atoms or molecules. achiral three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image chiral. Each of our hands is Isomers WebStep 1: Give each atom connected to the chiral center a priority based on its atomic number. The higher the atomic number, the higher the priority. So, based on this, bromine gets priority one, the oxygen gets priority two, the methyl carbon is the third and the hydrogen is the lowest priority-four: Step 2:

This geometric property is called … See more The chirality of a molecule is based on the molecular symmetry of its conformations. A conformation of a molecule is chiral if and only if it belongs to the Cn, Dn, T, O, I point groups (the chiral point groups).
