Which of the following is not a priority rule for R, S-Configuration?
(a) If the four atoms attached to the chiral centre are all different, priority depends on atomic number, with the atom of lower atomic numbers getting lower priority
(b) If the two atoms attached to chiral centre are same, the atoms attached to each of these first atoms are compared
(c) When there is a double bond or triple bond, both atoms are considered to be duplicated or triplicated
(d) If the four atoms attached to the chiral centre are all different, priority depends on atomic number, with the atom of higher atomic numbers getting lower priority
I got this question by my school teacher while I was bunking the class.
This interesting question is from R, S- Configuration and Water Softening in chapter Structure and Stereostructure of Molecules of Engineering Chemistry I
