Which of the following represent the correct sequence of indicated property ? .A. `a.Mn^(2+)ltNi^(2+)ltCo^(2+)ltFe^(2+)`: magnetic momentB. `b.FeOgtCoOgtNiO`:basic characterC. `c.ScltTiltCrltMn`: number of oxidation statesD. `d.1.73mu:` one unpaired electrons

Answer» Correct Answer - B::C::D
The number of unpired electrons of the ions in the give choices are
`Mn^(2+) (n=5),Ni^(2+) (n=2),Co^(2+) (n=3)` and `Fe^(2+)(n =4)` .
