[Fe(H2O)6]2+ and [Fe(CN)6]4- differ in:
1. Geometry and magnetic moment.
2. Geometry and hybridization.
3. Magnetic moment and colour.
4. Hybridization and number of d-electrons.
Aqueous solution of Ni2+ contains [Ni(H2O)6]2+ and its magnetic moment is 2.83 BM. When ammonia is added in it, the magnetic moment of solution:
1. Will remain the same.
2. Will increase from 2.83 BM.
3. Will decrease from 2.83 BM.
4. Cannot be predicted theoretically.
[Co(NH3)4(NO2)2]Cl can show:
