(Br2)2+ Paramagnetic or Diamagnetic

Postby Dake Huang 4A » Tue Dec 09, 2014 11:43 pm

Is (Br2)2+ diamagnetic or paramagnetic, in the final it saids diamagnetic but I think it is paramagnetic, if it is diamagnetic can someone please explain to me why?

Which final are you talking about? I drew a molecular orbital diagram for (Br2)2+ and agree with you; it is paramagnetic with unpaired electrons in its 3pi*x orbital and 3pi*y. If the question was asking about just Br2 then it would be diamagnetic because the two electrons we took away to form 2+ would be able to fill those shells.

In the fall 2013 final it says it is diamagnetic.

It's a mistake. It's paramagnetic. Lavelle replied here: viewtopic.php?f=43&t=8834&p=22074&hilit=br2&
