How do we compare the "intensity of colors of coordination compounds"? If for example we consider octahedral complexes, does a higher $\Delta_o$ mean more intense color or less intense color?
@AshishAhuja I think higher $\Delta_o$ would mean that compound would absorb light of lower wavelength (higher energy) , so light consisting more higher wavelengths (lower energy) would be reflected meaning brighter colors
Answer of it should've been 3 according to me but answer is given as 6
hmm yes I think what you say makes sense.. higher intensity means higher overall energy, which means more amount of non-absorbed light in lower wavelength region hence (3).
But judging energy gap between H2O and CN ones seems difficult , as tetrahedral and octahedral comparison and strength of ligand goes in opposite direction
also, the only way I can come up with for 6 moles of HI to be used in that question above is if all the -OH in 1,2,3-trihydroxybenzene get protonated.. although I still think the answer should be 3.
@Wolgwang it shouldn't be ig, the enol one will be less stable and thus have higher energy since the solvent is water it will make hydrogen bond with the carbonyl thus resulting in less intramolecular hydrogen bonding
