WebJan 23, 2024 · Hydrogen is the lowest possible priority substituent, because it has the lowest atomic number. When dealing with isotopes, the atom with the higher atomic mass receives higher priority. When visualizing the molecule, the lowest priority substituent should always point away from the viewer (a dashed line indicates this).
