Which of the following complexes exhibits the highest paramagnetic behaviour? Where gly = glycine, en = ethylenediamine and bpy = bipyridyl moities). (At. number

\mathrm{Ti}

=22, \mathrm{~V}=23, \mathrm{Fe}=26, \mathrm{Co}=27

)

Options

A\left[\mathrm{Ti} $\left(\mathrm{NH}_3\right)_6\right]^{3+}$
B\left[\mathrm{V} \text{ (gly) } 2(\mathrm{OH})_2 $\left(\mathrm{NH}_3\right)_2\right]^{+}$
C\left[\mathrm{Fe}(\mathrm{en})(\mathrm{bpy}) $\left(\mathrm{NH}_3\right)_2\right]^{2+}$
D $\left[\mathrm{Co}(\mathrm{OX})_2(\mathrm{OH})_2\right]^{-}$

Correct answer

D. $\left[\mathrm{Co}(\mathrm{OX})_2(\mathrm{OH})_2\right]^{-}$
