Question

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 of low spin. ( III ) with strong field ligands, Mn II complexes can be low spin. ( IV ) aqueous solution of Mn II ions is yellow in color. The correct statements are :

TestHub · Accepted Answer

With weak field ligands Mn(II) will be of high spin and with strong field ligands it will be of low spin. Ni(II) tetrahedral complexes will be genrally of high spin due to ${sp}^{3}$ hybridisation. It can very rarely be of low spin when ligand field is very strong.

Mn(II) is of light pink color in aqueous solution.
