  • Question 1
    1 / -0

    Which of the following pairs represents linkage isomers?

    Solution

    Linkage isomerism is shown by ambidient ligand like NCS and SCN 
    ∴ [Pd(P Ph3) (NCS2)] and [Pd(PPh3)2 (SCN)2] 
    Hence, option B is correct.

  • Question 2
    1 / -0

    The two compounds sulphato penta-ammine cobalt (III) bromide and sulphato penta-ammine cobalt (III) chloride represent :

    Solution

    Sulphato penta-ammine cobalt (III) bromide 
    [Co(NH3)5SO4] Br 
    Sulphato penta-ammine cobalt (III) chloride 
    [Co(NH3)5SO4] Cl 
    Both are separate compound does not show any type of isomerism.

  • Question 3
    1 / -0

    Increasing order of Δ0 of the following complex is –

    Solution

    For the same cation, stronger the ligand, higher the value of Δ0. Of the given ligands, NO2- is the stronest field ligand while H2O is the weakest field ligand. So, the correct order of given complexes is

    [Cr(H2O)6]+ 3 < [Cr(NH3)6]+3 < [Cr(NO2)6]–3

  • Question 4
    1 / -0

    When excess of ammonia is added to CuSO4 solution, the deep blue coloured complex is formed. Complex is –

    Solution

    CuSO4 + 4NH3→[Cu(NH3)4]–2 
    The compound is paramagnetic and square planar.

  • Question 5
    1 / -0

    The number of geometrical isomers of [Co(NH3)3(NO3)3] are:

    Solution

    Co(NH3)3(NO3)3 has 2 isomers: facial and meridional forms.
