CIP stereodescriptor swap-parity framework: (−1)^N signature under transposition of ranked substituents

Layer 2 — Chemistryin the chemical-nomenclature subtree

Cahn-Ingold-Prelog stereodescriptor parity under transposition: the R/S descriptor at a stereocentre is invariant under any even permutation of the four CIP-priority-ranked substituents and flipped under any odd permutation. Formally, the…
