What is the coordination number and oxidation state of aluminium in the complex ion [Al(H2O)4(OH)2] +?
Write all the isomers of |Pt(SCN) (NH3)3] (SCN).
The ligand SCN– is capable of linking itself through two atoms, viz S(–SCN) and N(–NCS), therefore the possible isomers are: [Pt(SCN)(NH3)3](SCN) and [Pt(NCS)(NH3)3] (SCN).
Name the ligands which are regarded as strong crystal fields and causes pairing of electrons.
