Question

Draw structures for the possible isomers of the six-coordinated compounds [Co(NH3)4Cl2] and [Co(NH3)3Cl3].

Answer 1

do you know what an isomer is?

Answer 2

it's referring to a molecule with the \(\sf \color{red}{same}\) formula but a \(\sf \color{blue}{different ~arrangement~of ~atoms}\). This also means different properties.

Answer 3

I don't know how to draw them

Answer 4

this is the general octahedral structure, just place the ligands on the letters in different ways (but so they are not the same geometrically).
