Can somebody provide details on ligand strength

Guys , can somebody provide their class notes or any source which makes clear which ligands act as strong/weak ones with different metals and oxidation states?

Just remember trik
C- kan(ear)
N- nakh (nose)
O- or
H- hath (hand)
C and N compound containg species will be strong and other will be week
See this trick work in my whole previous 40 year question of jee
