Which of the following is not the priority rule for R, S Configuration?

#Section 2: General Biology

  1. If the four atoms attached to the chiral center are all different, priority depends on atomic number, with the atom of lower atomic number getting lower priority.

  2. If the two atoms attached to chiral centers are same, the atoms attached to each of these first atoms are compared

  3. When there is a double bond or triple bond, both atoms are considered to be duplicated or triplicated

  4. If the four atoms attached to the chiral center are all different, priority depends on atomic number, with the atom of higher atomic number getting lower priority.
