Complex 2 shows two IR spectral bands at 1310 and 1430 cm-1, whereas complex 3 shows the same at 1065 and 1470 cm-1. X, Y and Z, respectively, are

Consider following statements regarding the magnetic moment of the 3d transition metal complexes:

A. Octahedral complexes of $$Mn^{II}$$​  (high spin) and $$Fe^{III}$$ (high spin) have $$\mu_{eff}$$ approximately equal to their $$\mu_{spin}$$ values.​

B. Tetrahedral complexes of $$Ni^{II}$$ and octahedral complexes of $$Co^{II}$$​ have orbital contribution added to their magnetic moments.

C. Orbital contribution is quenched for metal ions having A or E ground state.

D. Octahedral complexes of $$Cu^{II}$$ have $$\mu_{eff} > \mu_{spin}$$ value at 300 K due to orbital contribution added to their magnetic moments​

For octahedral geometry the triad with no net gain in CFSE, when the ligand field changes from weak to strong, is:

The correct statement for the CO and $$N_2$$ ligands in the complexes trans – $$[lrCl(CO)(PPh_3)_2]$$ and $$tranws-[lrCl(N_2)(PPh_3)_2]$$ is:​
