Amongst the following ions which one has the highest magnetic moment value?
(i) `[Cr(H_(2)O)_(6)]^(3+)`
(ii) `[Fe(H_(2)O)_(6)]^(2+)`
(iii) `[Zn(H_(2)O)_(6)]^(2+)`

[Fe(H_(2)O)_(6)]^(2+) is

Conjugate base of [AI(H_(2),O)_(6)]^(3+), is

The colour of [Ti(H_(2)O)_(6)]^(3+) is due to

The hybridisation of 'Al' in [Al(H_(2)O)_(6)]^(3+) is

Write down the IUPAC name for each of the following complexes and indicate the oxidation state, electronic configuration and coordination number. Also give stereochemistry and magnetic moment of the complex: (i) K[Cr(H_(2)O)_(2)(C_(2)O_(4))_(2)].3H_(2)O (ii) [Co*NH_(3))_(5)Cl.]Cl_(2) (iii) CrCl_(3)(py)_(3) (iv) Cs[FeCl_(4)] (v) K_(4)[Mn(CN)_(6)]

The correct order of the increasing magnetic moments for the following ions is NiCl_(4)^(2-) , Fe(H_2O)_(6)^(2+) , Ni(CN)_(4)^(2-) , Cu(H_2O)_(6)^(2+)

What can be inferred from the magnetic moment values of the following complex species ? {:("Example","Magnetic Moment (BM)"),(K_(4)[Mn(CN)_(6)]," 2.2"),([Fe(H_(2)O)_(6)]^(2+)," 5.3"),(K_(2)[MnCl_(4)]," 5.9"):}

Specify the oxidation numbers of the metals in the following coordination entities: (i) [Co(H_(2)O)(CN)(en)_(2)]^(2+) (ii) [CoBr_(2)(en)_(2)]^(+) (iii) [PtCl_(4)]^(2-) (iv) K_(3)[Fe(CN)_(6)] (v) [Cr(NH_(3))_(3)Cl_(3)]

All the following complex ions are found to be paramagnetic P=[FeF_(6)]^(3-) Q=[CoF_(6)]^(3-) R=[V(H_(2)O)_(6)]^(3+) S=[T:(H_(2)O)_(6)]^(3+) The correct order of their paramagnetic moment (spin only) is
