It is an odorless, colorless and tasteless gas. Available here. Q2741198. Reaction is given below –, Now let’s discuss industrial methods of production of carbon monoxide –, From carbon – In industries, the main source of carbon monoxide is producer gas. In a related reaction, the hydrogenation of carbon monoxide is coupled to C-C bond formation, as in the Fischer-Tropsch process where carbon monoxide is hydrogenated to liquid hydrocarbon fuels. As it reacts with iron of hemoglobin and forms carboxyhemoglobin in the blood. The carbon monoxide molecule contains a total of 1 bond(s) There are 1 non-H bond(s), 1 multiple bond(s) and 1 triple bond(s). Action with NaOH ( caustic soda): When carbon monoxide is heated with sodium hydroxide then sodium formate is formed. Phosgene is produced by using carbon monoxide. Only 25mg of CO is soluble in one liter of water at 25 ℃. Humans die within minutes when they inhale it. It is flammable and toxic gas so it must be handled very carefully. Carbon monoxide has been proposed for use as a fuel on Mars. STRUCTURE OF CARBON MONOXIDE. He heated zinc oxide (ZnO) with coke to produce CO.
