Among the following complexes (K-P)K3[Fe(CN)6] (K), [Co(NH3)6]Cl3 (L), Na3[Co(oxalate)3] (M),[Ni(H2O)6]Cl2 (N), K2[Pt(CN)6] (O) and [Zn(H2O)6](NO3)2 (P)the diamagnetic complexes are

  • Solution

The complex showing a spin-only magnetic moment of 2.82 B.M. is :

  • Solution


The correct structure of ethylenediaminetetraacetic acid(EDTA) is

  • Solution

The ionisation isomer of [Cr(H2O)4Cl(NO2)]Cl is

  • Solution

    Ionisation isomer of [Cr(H2O)4Cl(NO2)]Cl is [Cr(H2O)4Cl2]NO2.

The spin only magnetic moment value (in Bohr magneton units) of Cr(CO)6 is

  • Solution

Both [Ni(CO)4] and [Ni(CN)4]2- are diamagnetic. Thehy bridisations of nickel in these complexes, respectively,are

  • Solution

The IUPAC name of [Ni (NH3)4] [NiCl4] is

  • Solution

    The correct IUPAC name of the given compound is tetramminenickel (II) - tetrachloronickelate (II) thus (c)is the correct answer.

Among the following metal carbonyls, the C–O bond order is lowest in

  • Solution

    An anioniccarbonyl complex can delocalise more electron density to antibonding pi-orbital of CO and hence, lowers the bond order.

Which of the following has an optical isomer

  • Solution

In which of the following complexes of the Co (at. no. 27),will the magnitude of Δo be the hightest?

  • Solution

    In octahedral complex the magnitude of Δo will be highest in a complex having strongest ligand. Out of the given ligands CN- is strongest. So, Δo will be highest for [Co(CN)6]3–. Thus option (a) is correct.
