Bonsoir, dans un qcm j'ai eu : l'hydrogénation catalytique en présence de platine etc...

Je me demandais à quoi sert la "platine" dans ce genre de réactions? 

Merci d'avance pour votre aide. 🙂

la plaque métallique va permettre de déposer tes 2 H (d'où la cis- addition) elle va servir également de catalyseur pour la réaction ! Elle est de différente nature platine ou nickel ou plomb
