Its anti-cancer activity comes from the:In Valence Bond Theory, an octahedral LOW-SPIN complex like [Co(NH3)6]³⁺ uses which hybridisation?In Crystal Field Theory, the 5 d-orbitals in an OCTAHEDRAL field split into:In the spectrochemical series, which ligand is the STRONGEST field?The unusual stability of EDTA-metal complexes is mainly due to the:The biological molecule HAEMOGLOBIN contains which metal at its centre?A COORDINATION COMPOUND consists of a central metal atom (or ion) BONDED to a set of surrounding molecules or The COORDINATION NUMBER of the central metal in a complex isA ligand that has ONLY ONE donor atom (which forms a single bond to the central metal) is calledIn the complex $[\mathrm{Co(NH_3)_5\,Cl}]\mathrm{Cl_2}$, the oxidation state of cobalt isETHYLENEDIAMINETETRAACETATE (EDTA) is a famous polydentate ligand. It isThe IUPAC name of $[\mathrm{Co(NH_3)_6}]^{3+}$ isIn CRYSTAL FIELD THEORY (CFT) for an OCTAHEDRAL complex, the five degenerate d-orbitals of the free metal ion $[\mathrm{Fe(CN)_6}]^{4-}$ has $\mathrm{CN^-}$ ligands, which are STRONG-FIELD ligands. The complex isCis-trans isomerism is observed inWhich of the following best states the CHELATE EFFECT?Coordination compounds of transition metals are often COLOURED. CFT explains this colour as arising from$[\mathrm{Ni(CO)_4}]$ is tetrahedral and diamagnetic. The oxidation state of nickel in this complex isThe HEXACYANIDOFERRATE(II) ion $[\mathrm{Fe(CN)_6}]^{4-}$ contains iron in oxidation stateWhich of the following coordination compounds shows OPTICAL ISOMERISM?
