For octahedral Mn(II) and tetrahedral Ni(II)
complexes, consider the following statements:
(I) both the complexes can be high spin.
(II) Ni(II) complex can very rarely be low spin.
(III) with strong field ligands, Mn(II) complexes
can be low spin.
(IV)aqueous solution of Mn(II) ions is yellow in
colour.
The correct statements are :
