Bonsoir !!!

 L'item B est vrai mais je ne comprends pas pourquoi la molécule 1 est plus acide que la 3, est-ce que quelqu'un pourrait m'expliquer svp ? 😬

Salut @Jojooooo ! 

 

Alors ta molécule 1 est plus acide que ta molécule 3 tout simplement parce que le groupement -O-CH3 de la molécule est donneur par effet mésomère (+M) et que les groupements donneurs diminuent l'acidité 😉
