carbon monoxide - 2025 ACF Fall

Tossup

Iodine and this ligand are complexed with iridium (10[1])to catalyze (10[1])the production of acetic acid from methanol in (10[1])the Cativa process. (10[1])Due to pi-backbonding, this ligand has the largest crystal-field (10[1])splitting (-5[1])parameter (10[2])in the spectrochemical (10[3]-5[1])series. (10[1]-5[1])This compound (-5[1])and hydrogen form (10[1])water gas, (10[2]-5[3])and (10[2])it (-5[1])is the primary (-5[2])reducing (10[1]-5[1])agent (10[1])in blast furnaces. (10[1]-5[3])Though it (-5[1])is (-5[1])not (10[1]-5[1])produced during (-5[2])complete (10[1])combustion, (10[2])incomplete (10[3]-5[1])combustion (10[8]-5[3])produces (10[4]-5[1])this (10[2])compound. (10[21]-5[1])This (10[3])compound binds (10[2])200 (10[1])times (10[1]-5[1])more (10[1])strongly (10[2]-5[1])to hemoglobin (10[4])than (10[4])oxygen, (10[8]-5[1])so low concentrations (10[2]0[1])can (10[1])lead (-5[1])to poisoning. (10[2])For 10 points, (10[1]-5[1])name this odorless (10[2])and colorless (10[1])gas (10[5])with formula (10[2])CO. (10[3])■END■ (10[14])

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