syncytio13 Posted January 5, 2020 Share Posted January 5, 2020 Salut ! Dans l'item C, on a une isomérie de position car l'effet inductif de l'acide carboxylique est éloigné de la double liaison (plus de 4 liaisons) ? https://zupimages.net/viewer.php?id=20/01/gxws.png Quote Link to comment Share on other sites More sharing options...
Ancien Responsable Matière Solution Liliputienne Posted January 5, 2020 Ancien Responsable Matière Solution Share Posted January 5, 2020 Tout à fait : conditions d’hydratation + COOH trop loin = Isomérie sur la double liaison Bon courage !

syncytio13 Posted January 5, 2020 Author Share Posted January 5, 2020 @Liliputienne Merci ! Tant que j'y suis, est-ce que tu pourrais me dire (si tu sais) si on peut avoir une liaison hydrogène à l'intérieur du COOH entre le -OH et le C=O ?
