ok, heres a doubt frm coordination compunds!! how do we identify a strong and a weak ligand??

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

You will have to know the spectrochemical series first.......
According to the spectrochemical series,
I- < Br- < S2- < SCN- < Cl- < NO3- < N3- < F- < OH- < C2O42- < H2O < NCS- < CH3CN < Pyridine < NH3 < Ethylenediamine < bipy (2,2'-bipyridine) < 1,10-phenanthroline < NO2- < PPh3 < CN- < CO
So compounds in the spectrochemical series determine whether the ligands are weak or strong.........bipin bhaiya had cleared it earlier.....i remember.

the general way to find out the strength of ligand is ......first know the donor atom in the ligand ,then follow the order that carbon donors>N donors > O donors..........ok
