In coordination complex compounds when does nh3 acts as strong ligand

Question

Umakant biswal · Answer

@ kumar
in spectrochemical series the ligands are arrenged in their increasing delta value towards a metal ion .
as the charge on the metal ion will increase the magnitude of delta alos increase .
there are a very few case in which nh3 is act as a weak ligands but generally its a strong ligand .
WHEN CHARGE ON THE METAL IS HIGHER , THEN ITS CONSIDERED AS STRONG LIGAND ,
AND WHEN CHARGE IS LOWER ITS CONSIDERED AS WEAK LIGAND .
example – in the case of co^2+ complexes it act as a weak field ligand .
in case of co ^3+ complexes it act as a strong field ligand .
