Given that the energy of the photons of different colours decreases in the order of VIBGYOR (Violet gt Indigo gt Blue gt Green gt Yellow gt Red ) and that if complex absorbs a photon of low energy then it shows colour of high energy photon. If an ion , M^(2+) , forms the complexes [M(H_(2)O)_(6)]^(2+),[MBr_(6)]^(4-), and [M(en)_(3)]^(2+) . The colours of the complexes, though not necessarily in order, are green, red, and blue. Match the complexes with the appropriate colour. ( Do not use the table of complementry colours for this question )
