Salut, est ce que quelqu'un pourrait m'expliquer et me dire si cette molécule a une configuration S ou R. 

Merci en avance :)

Bonjour @PASSofia

 

il faut d'abord identifier les carbones asymétrique (en orange ) : https://postimg.cc/MnvScm03

Puis mettre les 4 substituant dans l'ordre de priorité :  priorité NH2 > COOH > CphOH  > H 

Puis on regarde si c'est R ou S : https://postimg.cc/kV81pTPH 

 

Si c'est pas clair dis moi :) 

Courage !
