Question

Explain [Co(NH3)6]3+ is an inner orbital complex whereas [Ni(NH3)6]2+ is an outer orbital complex.

Explain

SolutionShow Solution

In the presence of NH3, the 3d-electrons of Co pair up to leave two vacant d-orbitals which in the case of [Co(NH3)6]3+ get involved in d2sp3 hybridisation forming the inner orbital complex. In [Ni(NH3)6]2+, nickel is in +2 oxidation state and its configuration is 28. In this, the outer orbital complex forms sp3d2 hybridisation.

Explain why \[\ce{[Fe(H2O)6]^{3+}}\] has magnetic moment value of 5.92 BM whereas \[\ce{[Fe(CN)6]^{3-}}\] – has a value of only 1.74 BM.

Why do compounds having similar geometry have different magnetic moment?

Assertion: \[\ce{[Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electrons.

Reason: Because it has d2sp3 type hybridisation.

Explain [Fe(CN)6]3− is an inner orbital complex, whereas [FeF6]3− is an outer orbital complex.
