Quick easy chem help

Based on the colors of their Cr (III) complexes, arrange the following ligands in a spectrochemical series in order of increasing value of the crystal field splitting Delta : acac^- (a bidentate ligand), acetate^-,C1^-,H_2O,NH_3, and urea. The colors of the Cr (III) complexes are red for Cr(acac)_3, violet for [Cr(H20)_6]^3+, green for [CrCl_2(H_2O)_4] ', green for [Cr(urea)A^6]^3+, yellow for [Cr(NH3)_6]^3+, and blue-violet for Cr(acetate)_3(H_2O)_3. Rank from smallest to largest. To rank items as equivalent, overlap them.

Explanation / Answer

Based on the crystal field splitting, the ranking of ligands would be,

smallest                                                  largest

     Cl- < acac- < acetate < urea < H2O < NH3
