Four molecules of this combine with nickel in an intermediate step of the Mond
 process.
Cytochrome P450 is so named because its complex with this compound has an absorption spectra
 maxima at 450 nanometers. Along with HCL, it is used in a Friedel-Crafts like reaction called the
 Gattermann-Koch reaction. Four molecules of this combine with nickel in an intermediate step of the Mond
 process. Along with hydrogen it is found in syngas and is consumed in the Fischer Tropsch process. When
 this compound binds hemoglobin, it increases hemoglobin's affinity for already bound oxygen, thus
 preventing oxygen from being distributed to the body. For 10 points, name this compound with one carbon
 and one oxygen atom.
