Could you please take this survey for my friend? It can be found here: http://www.makesurvey.net/cgi-bin/survey.dll/D0015938F32C4F9CB7EE354921498C1C Please and thank you so, so, so much. ~Avagadbro

I would just like to know why the cis and trans forms of [Co(NH3)4Cl2]Cl are different colors. Or just point me in the right direction. Thanks.

So I have this group assignment (working with other people sucks) where I have to find out "...how isomerism leads to differences in the property of a named complex." I have done some research. All the places I have looked so far have stated that there are differences with respect to chemical, optical and magnetic properties, but they do not go into detail as to why. So, a little help? Please and thank you.
