$4\mathrm{.}6$ Construct a spectrochemical series for ligands $x^{n-}$ from the following wavelengths of maximum absorption $(\frac{{}_{\text{m}\text{a}\text{x}}}{n}m)$ for the respective cobalt$($III$)$ pentaammine derivatives $[Co(N{H}_3{)}_{5}x{]}^{3-n}+$ in aqueous solution, and discuss the order in which these ligands appear. Compare the ligand spectrochemical series shown in the top half of Fig. $4\mathrm{.}4($p$\mathrm{.}49)$ with your cobalt$($III$)-$series, and comment on any differences.
