Statement II: Me group is having +I effect while F atom is having –I effect
3. Statement I: [Cr(H2O)6]+3 is more acidic compared to [Fe(H2O)6]+3
Statement II: Both are inner orbital complexes
4. Statement I: Only cis [Pt(NH3)2Cl2] react with oxalic acid (H2C2O4) to form [Pt Cl2(OX)]−2 not the trans isomer
Statement II: The oxalate ion is a bidentate ligand which occupies adjacent positions only
5. Statement I: Under the strong field ligand only the degeneracy of the d-orbitals is lost
Statement II: After splitting of the d-orbitals also Hund’s rule is not violated any where
6. Statement I: NO is three-electron donor Statement
II: The anti-bonding electron in NO is very much susceptible to donate extra to its lone pair
7. Statement I: SnCl2 does not act as ligand but SnCl3− acts as good ligand
Statement II: On addition of Cl- to SnCl2 orbital containing the lone pair acquires less s-character
8. Statement I: Under the influence of a strong field ligand, d7-system will have only one unpaired electron either in coordination number six or four

9. Statement I: [Co(en)2(NH3)Br]SO4 has lower electrical conductivity as compared to [Co(en)2(NH3)SO4]Br
Statement II: Both the complexes produce the same number of ions in solution
10. Statement I: -NO2 and -CN are ambidentate ligands
Statement II: An ambidentate ligand has two sites on different species available for coordination but only one is used at a time
11. Statement I: All inner orbital complexes are diamagnetic
Statement II: Inner orbital complexes may or may not contain unpaired electrons
12. Statement I: In octahedral complexes, the three t2g- orbitals are stable and of low energy while the two eg- orbitals are unstable and have high energy
Statement II: In octahedral complexes, the three t2g- orbitals experience less repulsion from the ligands while two eg- orbitals experience more repulsion from the ligands due to their orientation

18. Statement I: K3[Fe(CN)6] is a low-spin complex
Statement II: In the presence of strong CN ligand, the d-electrons are rearranged
19. Statement I: The geometrical isomers of the complex [M(NH3)4Cl2] are optically inactive
Statement II: Both geometrical isomers of the complex [M(NH3)4Cl2] possess axis of symmetry
