il y a une heure, Keox a dit :

Hello

pourquoi la molécule 3 est plus basique que la 2 ?

Merci d'avance :)

 

coucou, 

 

La molécule 2 présente un effet mésomère +M qui diminue la basicité contrairement à la molécule 3.

Donc 3 est plus basique que 2.

 

N'hésite pas si tu as encore des questions :)
