lactone

Comment nommer les lactones ?
La façon la plus courante de nommer les lactones est celle donnée en premier dans le tableau ci-dessous : - Les positions α,β,γ,d,ε, correspondent à la position du groupe hydroxy par rapport au groupe carboxyle dans l'hydroxyacide correspondant.
Le cycle contient 2 carbones c'est une α-lactone.
Liaison ester : qu'est-ce que c'est ? Liaison entre un groupe alcool (-OH) et un groupe acide carboxylique (-COOH), formée par élimination d'une molécule d'eau (H₂O).
