The correct order of increasing field strengths

Spectrochemical series is a series in which ligands are arranged in order of increasing field strength.

${\mathrm{I}}^{-}<{\mathrm{Br}}^{-}<{\mathrm{SCN}}^{-}<{\mathrm{Cl}}^{-}<{\mathrm{S}}^{2-}<{\mathrm{F}}^{-}<{\mathrm{OH}}^{-}<{\mathrm{C}}_2{\mathrm{O}}_4^{2-}<{\mathrm{H}}_2\mathrm{O}<{\mathrm{NCS}}^{-}<{\left(\mathrm{edta}\right)}^{4-}<{\mathrm{NH}}_3<\mathrm{en}<{\mathrm{CN}}^{-}<\mathrm{CO}$
