A solution of [Ni(H2O)6]2+ is green, but a solution of [Ni(CN)4]2– is colorless because:
1. | There are paired electrons in [Ni(H2O)6]2+ while all electrons are unpaired in [Ni(CN)4]2– |
2. | There are unpaired electrons in [Ni(H2O)6]2+ while all electrons are paired in [Ni(CN)4]2– |
3. | There are unpaired electrons in [Ni(H2O)6]2+ and [Ni(CN)4]2– |
4. | None of the above. |
