Salut! 

Je me sens un peu conne (-_-) parce que c'est du S1 mais la mlcl de l'énoncé me pose problème. On nous parle du : (2E, 3R)-3,4-diméthylhex-2-ène.

J'arrive pas a comprendre comment elle peut être 2E et 3R vu que la double liaison serait entre le carbone 2 et 3, donc le 3 ne devrait pas être asymétrique? 

Si qlqn peut m'expliquer?
