Carbon Monoxide is More Dangerous than Carbon Dioxide

[caption id="attachment_5355" align="alignright" width="440"] Carboxyhemoglobin - CCA SA 3.0 Unported by Rifleman 82[/caption] Human and animal life requires an exchange of oxygen (O2) and carbon dioxide (CO2). If the atmosphere contains more than a minimum of carbon monoxide (CO), life is at risk. Why? Consider the properties that distinguish carbon dioxide from the monoxide. Carbon Dioxide Carbon dioxide contains two atoms of oxygen bonded to one atom of carbon. The structure is written O=C=O. The length of its double bonds is 116.3 picometers. Bonding is covalent, not ionic. Water solubility at 250C is 1.45 g/l. Carbon Monoxide Carbon monoxide is written simply C≡O. The triple bond is 112.8 picometers. It consists of two polar covalent bonds plus a coordinate covalent bond. Its dissociation energy is 1072 kilojoules per mole. Water…
