Which of the following reactions is not described correctly?

Options

A. `CO(g)+S(s) rarr COS(g)`
B. `Fe+9CO underset("under pressure")overset(200^(@)C)rarr Fe(CO)_(9)`
C. `CO(g) + Cl_(2)(g) rarr COCl_(2) (g)`
D. `2CO(g)+O_(2)(g)rarr 2CO_(2)(g)`

Answer

B

Explanation

`Fe + 5CO underset("under pressure")overset(200^(@)C)rarr Fe(CO)_(5)`
`2Fe(CO)_(5) overset("Photolysis")rarr Fe_(2)(CO)_(9) + CO`
Carbon monoxide is quite reactive, it burns with a .blue flame to carbon dioxide. It reacts with `Cl_(2)` gas in the presence of light or hot charcoal, which serve as catalysts, to give carbonyl chloride `(COCl_(2))` which is especially useful as a starting material for the synthesis of polycarbonates that are widely used as tough low - density transparent materials. When carbon monoxide is passed over heated sulphur, the compound carbonyul sulphide `(COS)`, a promising low - hazard fungicide, is formed.
