Question : 19 of 100

Marks: +1, -0

Among the statements(a)-(d), the incorrect ones are-

(a) Octahedral Co(III) complexes with strong field ligands have very high magnetic moments

\Delta_0 < P

, the d-electron configuration of Co(III) in an octahedral complex is

t_{eg}^4 e_g^2

(c) Wavelength o f light absorbed by

[\mathrm{Co}(\mathrm{en})_3]^{3+}

is lower than that of

[\mathrm{CoF}_6]^{3-}

\Delta_0

for an octahedral complex of Co(III) is 18,000 cm

^{-1}

, the At for its tetrahedral complex with the same ligand will be 16,000

\text{cm}^{-1}
