When utilizing the universally accepted Cahn-Ingold-Prelog (CIP) sequence rules, which of the follow — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

The CIP rules strictly rely on atomic number, not steric bulk or mass (unless distinguishing isotopes, where higher mass wins, e.g., D > H). Multiple bonds are treated as multiple single bonds to that specific element type. The sequence dictates walking outward atom-by-atom until the very first point of atomic difference is established.
