Bonjour, pourriez vous m'expliquer pourquoi cette molécule n'est pas le 3E2R 2bromo-pent-3ène car la somme des indices ici fait 5 alors qu'elle fait 6 dans cet item...

Merci beaucoup +++

Coucou, la double liaison est prioritaire donc elle doit avoir le nombre le plus petit possible. Ici, on ne s’occupe pas de la somme des indices.
