प्रश्न
Why do compounds having similar geometry have different magnetic moment?
Advertisements
उत्तर
It is due to the presence of weak and strong ligands in complexes, if \[\ce{CFSE}\] is high, the complex will show low value of magnetic moment and vice versa, e.g. \[\ce{[CoF6]^{3-}}\] and \[\ce{[Co(NH3)6]^{3+}}\], the former is paramagnetic and the latter is diamagnetic.

Magnetic moment of \[\ce{[MnCl4]^{2-}}\] is 5.92 BM. Explain giving reason.
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.
Assertion: \[\ce{[Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electrons.
Reason: Because it has d2sp3 type hybridisation.
The correct order of magnetic moment (spin only value in B.m.) is:
