Question

A very pure form of carbon monoxide can be obtained from:
A.Sodium hexacyanoferrate
B.Sodium oxalate
C.Formic acid
D.Nickel tetracarbonyl

Answer 1

Hint: To answer this question, you should recall the concept of preparation of carbon monoxide.
Carbon monoxide is an inorganic non-metallic compound. It is used as a marker of respiratory status in spirometry tests, a food additive for pigment fixation in meat. Carbon monoxide exists in all eukaryotes, ranging from yeast to humans. In humans, carbon monoxide is involved in the porphyrin metabolism pathway.

Complete Step by step solution:
From, the given options it is evident that: Nickel carbonyl (IUPAC name: tetracarbonylnickel) is the organonickel compound with the formula \[Ni{\left( {CO} \right)_4}\] ​. It is a pale-yellow liquid and is the principal carbonyl of nickel. It is formed as an intermediate in the Mond process for the purification of nickel and a reagent in organometallic chemistry. It is considered one of the most toxic substances in industrial processes. As it, an intermediate in the Mond process, pure forms of carbon monoxide and nickel are obtained by heating of \[Ni{\left( {CO} \right)_4}\] .
Therefore, we will conclude that the right answer to the present question is option D.

Additional Note: Carbon monoxide when breathed is harmful because it displaces oxygen in the blood and deprives oxygen of the heart, brain and other vital organs. In minutes, massive quantities will overtake a person without warning, causing them to lose consciousness and suffocate. A particular danger to the fetuses is also poisoning. Carbon monoxide is a combustion by-product, present any time fuel is burned. Popular home appliances, such as gas or oil furnaces, gas refrigerators, gas clothing dryers, gas ranges, gas water heaters or space heaters, fireplaces, charcoal grills, and wood-burning stoves are made. Carbon monoxide has positive and adverse effects on humans. Increased levels of carbon monoxide in red blood cells decrease the amount of oxygen haemoglobin carries throughout the body. The effect is that vital organs like the brain, nervous tissues, and the heart don’t get enough oxygen to function properly.

Note: Carbon monoxide can also form due to incomplete combustion reactions. It is a stable ligand and forms many complexes with transition metals.
