Carbon donor ligands are strong ligands and usually form low spin complexes. Among the complexes given below,select the high spin complex.

The correct order of ligands arranged in increasing field strength.

Given below are two statements $:$
Statement $(I) :$ In octahedral complexes,when $\Delta_{o} < P$ high spin complexes are formed. When $\Delta_{o} > P$ low spin complexes are formed.
Statement $(II) :$ In tetrahedral complexes because of $\Delta_{t} < P$,low spin complexes are rarely formed.
In the light of the above statements,choose the most appropriate answer from the options given below $:$

Complexes containing halide ligands are generally .....

Which relationship is correct for the crystal field splitting energy between octahedral $(\Delta_0)$ and tetrahedral $(\Delta_t)$ complexes?

Homoleptic octahedral complexes of a metal ion $M^{3+}$ with three monodentate ligands $L_1, L_2$ and $L_3$ absorb wavelengths in the region of green,blue and red respectively. The increasing order of the ligand strength is:
