Answers

1.(c) The complex [CoBr(NH_{​​​​​3}​)₅]SO​​​_{​​​​​4} have a linkage isomerism.

[Co(NH3)5(SO4)]Br and [Co(NH3)5Br]SO4

2. (a) The complex [No(en)₃]²⁺ show optical isomerism.

3. (c) Crystal field theory use to explain the splittingl of the

d-orbital energy levels due to electrostatic interactions

between the metal and ligands.

4. (c) In the octahedral complex [Cr(OH_{​​​​​2}​​​​)₆]²⁺ d_{​​​​x² -y^{2 and dz2}} are higher in energy.

5. (b) In the complex [Fe(CN)6] the d​​​​​​x​​​​​​​​​​2 - y​2 and dz2 orbits are higher in energy.
