Question

The formula of phosgene is \[COC{{l}_{2}}\] . if true enter $1$ , else $0$.

Answer 1

Hint:Phosgene is a poisonous gas which is prepared by the reaction of carbon monoxide with chlorine gas . It is a colourless gas in low concentrations, it’s order resembles that of freshly cut hay or grass. Phosgene may be valued as an industrial building block, especially for the assembly of urethanes and polycarbonate plastics.

Complete step by step answer:
The production of phosgene gas takes place when purified carbon monoxide gas and chlorine gas passes through a bed of porous activated charcoal.
$CO+C{{l}_{2}}\to COC{{l}_{2}}$ , $\Delta {{H}_{reaction}}=-107.6kJ/mol$
Phosgene is the organic compound with the formula$COC{{l}_{2}}$.
This is an exothermic reaction. This reaction is conducted between $50$ and $150{}^\circ C$. Above $200{}^\circ C$, phosgene reverts to carbon monoxide gas and chlorine, ${{K}_{eq}}\left( 300K \right)=0.05$ Phosgene remains considered a viable chemical operations agent because it’s very easy to manufacture in comparison to the assemble requirement of more technically advanced chemical weapons like the first generation nerve gas .
Ultraviolet gas (UV) radiation in the presence of oxygen, chloroform slowly converts into phosgene by radical reaction.
The phosgene gas is also produced by decomposing Freon $-22$ after flames ducted up from a gas fire need an air-conditioning unit on the roof and ruptured a nose.
Hence from the above information we can say that the given statement is true. Answer is \[1\].

Additional Information:
Phosgene can also be produced during testing for leaks of older-style refrigerant gases. Chloromethane was formerly leak-tested in place by employing a little gas torch (propane, butane or propylene gas) with a sniffer tube and a copper reaction plant within the flame nozzle of the torch.

Note:
In the research laboratory phosgene still finds limited use in organic synthesis. A variety of substitutes have been developed, like bis (tri-chloromethyl) carbonate (triphosgene) a crystalline substance.
