Among the statements(a)-
A
Octahedral Co(III) complexes with strong field ligands have very high magnetic moments and and
B
When Δ 0 < P, the d-electron configuration of Co(III) in an octahedral complex is 
and only
and only
C
Wavelength of light absorbed by [Co(en) 3 ] 3+ is lower than that of [CoF 6 ] 3– only and
D
, the incorrect ones are : If the Δ 0 for an octahedral complex of Co(III) is 18,000 cm –1 , the Δ t for its tetrahedral complex with the same ligand will be 16,000 cm –1 only only
Text Solution
Verified by ExpertsThe correct answer is:
D
with a strong field complex forms a low magnetic moment complex.
If 
, the configuration of 
will be 
.
CFSE of 
is more than that of 
. It implies that 
absorbed of 
is less than that of
.
Hence, statements and are incorrect.
