Can the trend of spectrochemical series vary/fluctuate according to the central metal atom (CMA) that is being used.For?
For example, for the CMA Ni^+2$\ce{Ni^2+}$ the ligand H20$\ce{H2O}$ will have more CFSE then NH3than $\ce{NH3}$ because NH3$\ce{NH3}$ acts as a WFLweak field ligand (WFL) for M^+2,$\ce{M^2+},$ even worse then H20$\ce{H2O},$ though NH3$\ce{NH3}$ is placed greaterhigher then H20$\ce{H2O}$ in the spectrochemical series.
