Which one of the following octahedral complexes will not show geometrical isomerism?(A and B are monodentate ligands)
(b) [MA5B] due to absence of symmetry of B cannot exist in the form of cis-trans-isomer.
According to IUPAC nomenclature sodium nitroprusside is named as
(b) IUPAC name of sodium nitroprusside Na2[Fe(CN)5NO] is sodium pentacyanoni trosyl ferrate(III) beacuse in it NO is neutral ligand and the oxidation number of Fe is +3. Which is calculated as

Amoung the following which is not the -bonded organomettalic compound?
IUPAC name of [Pt(NH3)3 (Br)(NO2)Cl]Cl is
The IUPAC name of [Pt(NH3)3 (Br)(NO2)Cl]Cl is triamminebromochloronitroplatinum(IV)Chloride
(Oxidation number of Pt=+4, and ligands are arranged in alphabetical order)
Which of the following cation does not form an ammine complex with excess of ammonia?
(d) Na+ does not possess the tendency to form complex ion because of non-availability of d-orbitals.
EDTA is a ligand.
EDTA (Ethylenediaminetetraacetic acid) is a hexadentate ligand, meaning it can form six coordinate bonds with a single metal ion. It has four carboxylate groups and two nitrogen atoms that can donate lone pairs, allowing it to bind to metal ions through multiple sites.
The coordination number of cobalt in[Co(en)2Br2]Cl2 is:
(c) Each en has two coordinate bonds; each Br has one coordinate bond
