Iodine and this ligand are complexed with iridium to catalyze the production of acetic acid from methanol in (10[1])the Cativa process. Due to pi-backbonding, this ligand has the largest crystal-field splitting parameter in the spectrochemical series. This compound and hydrogen form water gas, and (10[1])it is the primary reducing agent in blast furnaces. (-5[1])Though it is not produced during complete combustion, incomplete combustion (10[1])produces (10[1]-5[1])this (10[1])compound. (10[1])This compound binds 200 (10[1])times more strongly to hemoglobin than oxygen, so low concentrations can lead to poisoning. For 10 points, name this odorless and colorless gas with formula CO.
