Round 2: Tossup 17

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 (-5[1])series. This compound and hydrogen form water gas, and it is the primary reducing agent in blast furnaces. Though it is not produced during complete combustion, incomplete (10[1])combustion produces this compound. (10[1]-5[1])This (10[1])compound binds 200 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. ■END■ (10[1])

ANSWER: carbon monoxide [accept CO until read; accept carbon monoxide poisoning; accept carbonyl ligand]
