  • Question 1
    1 / -0

    The correct order for the wavelengths of absorption of the complexes of nickel in the visible region is

    Solution

    The order of the ligands in terms of splitting caused by them (Spectrochemical series) is H2O < NH3 < NO2. 

    Greater the octahedral splitting, higher will be the energy barrier created for the electrons showing the d-d transitions, and shorter the wavelength of the light adsorbed.

    The correct order of the wavelengths of absorption of complexes of nickel in the visible region is [Ni(NO2)6]4- < [Ni(NH3)6]2+ < [Ni(H2O)6]2+.

     

  • Question 2
    1 / -0

    The number of unpaired electrons in the complex ion [CoF6]3- (Atomic number Co = 27) is

    Solution

    Valence shell electronic configuration of Co(27) = [Ar] 3d7, 4s2

    Valence shell electronic configuration of Co3+(24) = [Ar] 3d6, 4s0

    The number of unpaired electrons in the complex ion [CoF6]3- is 4.

     

  • Question 3
    1 / -0

    In the complexes [Fe(CN)6]3- and [Fe(C2O4)3]3-, the respective co-ordination numbers of Iron is

    Solution

    In both the complex the coordination of iron is 6 each.

  • Question 4
    1 / -0

    Which of the following does not have a metal carbon bond?

    Solution

    There is no metal- carbon bond in Al(OC2H3)3. Metal is attached to oxygen in compound.

     

  • Question 5
    1 / -0

    Which of the following will not show geometrical isomerism?

    Solution

    [CO (NH3)5NO2] Cl2 will not show geometrical cis-trans isomerism due to symmetrical structure of the complex.
