The bond angle of 160 degrees for CO-leghaemoglobin is in conflict with recent spectroscopy results on myoglobin but is consistent with angles obtained for myoglobin X-ray crystal structures. Above 800 °C, CO is the predominant product: O2 + 2 C → 2 CO (ΔH = −221 kJ/mol) Since there are just two atoms the molecule is lines with no bond angle. The notable exceptions are the compounds CN (cyanide) and CO (carbon monoxide), which the bond is polar due to the unequal sharing of electrons between the two atoms in the structure.

The histidine prevents the heme/carbon monoxide bond from being irreversibly lethal. Phosgene, useful for preparing isocyanates, polycarbonates, and polyurethanes, is produced by passing purified carbon monoxide and chlorine gas through a bed of porous activated carbon, which serves as a catalyst. If carbon used only atomic orbitals with one electron, its compound with hydrogen would be CH 2, and the H-C-H bond angle would be 90° (the angle between two p orbitals). Without more context it was also often taught that the bond order in CO is three, since there are eight electrons in bonding orbitals and two in anti-bonding orbitals. 180° The methane molecule has a bond angle.
