Concept explainers
a)
Interpretation:
R and S configuration is to be assigned to the molecules by re-orienting the substituent.
Concept introduction:
Rule 1:
a) Higher
b) An atom node duplicated closer to the root ranks higher than one duplicated further.
Rule 2: Higher
Rule 3: Z precedes E and this precedes nonstereogenic (nst) double bonds.
Rule 4:
a) Chiral stereogenic units precede pseudoasymmetric stereogenic units and these precede nonstereogenic units (R = S > r = s > nst).
b) When two ligards have different descriptor pairs, the one with the first chosen like descriptor pairs has priority over the one with a corresponding unlike descriptor pairs.
c) r precedes s.
Rule 5: An atom or group with descriptor R has priority over its enantiomorph S.
b)
Interpretation:
R and S configuration is to be assigned to the molecules by re-orienting the substituent.
Concept introduction:
Rule 1:
a) Higher atomic number precedes lower.
