The correct order (weak Chlorophyll, haemoglobin and vitamin B₁₂ are coordination compounds of:Among the following complexes
$\mathrm{K}_3[\mathrm{Fe}(\mathrm{CN})_6](\mathrm{K}),[\mathrm{Co}(\mathrm{NH}_Ethylenediamine (en) is best described as a:The biological molecule HAEMOGLOBIN contains which metal at its centre?A COORDINATION COMPOUND consists of a central metal atom (or ion) BONDED to a set of surrounding molecules or The COORDINATION NUMBER of the central metal in a complex isA ligand that has ONLY ONE donor atom (which forms a single bond to the central metal) is called$[\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 is
