WebExample: but-2-ene. Isomer 1 : Step 1 : split the alkene. Step 2 : assign the relative priorities. The two attached atoms are C and H, so since the atomic numbers C > H then the -CH3 group is higher priority. Step 3 : look at the relative positions of the higher priority groups : same side = Z, hence (Z)-but-2-ene. Isomer 2 : WebE and Z configurations E and Z configurations in organic chemistry refer to the relative spatial arrangement of atoms or groups of atoms in a molecule. These configurations are used to describe the stereochemistry of a molecule, which is the study of the three-dimensional arrangement of atoms in a molecule. we will explore the concept of E and Z …
