Iodine and this ligand are complexed with iridium to catalyze the production of acetic acid from methanol in 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, (-5[1])and it is the primary reducing agent in blast furnaces. (10[1])Though it is not produced during (-5[1])complete combustion, incomplete combustion (10[1])produces this compound. (10[3])This compound binds (10[1])200 times more strongly to hemoglobin (10[1])than (10[1])oxygen, (10[1])so low concentrations (0[1])can (10[1])lead to poisoning. For 10 points, name this odorless and colorless gas with formula CO. ■END■ (10[1])
