Q

What is the sequence rules of preferred atoms or groups to determine polarity (Z or E) of an atom?

A
  • priorities assigned to groups based on atomic number
  • where two atoms are the same, consider what is attached to each of them
  • one atom or a higher atomic number takes precedence over several of a lower atomic number
  • two atoms of a particular atomic number take precedence over one atom of the same atomic number
  • double bonds are treated as two single bonds
