Salut, je ne comprends pas pourquoi l'atome SO3 possède un moment dipolaire global nul, on a bien 3 liaisons avec 3 atomes identiques on pourrait dire apolaire or il y a un doublet non liant donc polaire = moment dipolaire non nul ?

Salut @chapeau,

Je te mets l'image de la molécule SO3 :

Il y a bien 3 liaisons avec 3 atomes identiques mais pas de doublet non liant au niveau du S. Le moment global dipolaire est donc bien nul.

J'espère avoir répondu à ta question ;)
