Which of the following complex ion is expected to absorb visible light? [CBSE AIPMT 2009]
Which of the following coordination entities should be expected to absorb light of lowest frequency?[AIIMS2009]
Assertion: CO and CN are referred as acid ligands. Reasaon: In CO and CN vacant type orbitals are present. [AIIMS 2009]
Assertion: K4[Fe(CN)6] is diamagnetic and [Fe(H2O)6]Cl3 is paramagnetic. Reason: Hybridisation of central metal in K4[Fe(CN)6] is sp3d2, while in [Fe(H2O)6]Cl3 is d 2sp 3. [AIIMS 2009]
Again for [Fe(H2O)6]Cl3, since H2O is a weak field ligand, the unpaired electrons will not get paired up. Thus the hybridization of Fe will besp 3d 2. So, the reason is not correct. Hence, the correct option is (c).
The coordination compound of which one of the following compositions will produce two equivalents of AgCl on reaction with aqueous silver nitrate solution? [J&K CET 2009]
The existence of two different coloured complexes with the composition [Co(NH3)4Cl2] + is due to [CBSE AIPMT2010]
Crystal field stabilisation energy for high spin d octahedral complex is [CBSE AIPMT2010]
Which of the following complex ion is not expected to absorb visible light? [CBSE AIPMT 2010]
Assertion: If 4 for [Cu(NH3)4] 2+ is 2.1 × 10 13, its instability constant is 4.76 × 10 –14. Reason: Overall dissociation equilibrium constant varies inversely with formation constant. [AIIMS2010]
