A) prevents aerial oxidation of chloroform
B) prevents decomposition of chloroform
C) decomposes phosgene to CO and \[C{{l}_{2}}\]
D) removes phosgene by converting it to ethyl carbonate
Correct Answer: D
Solution :
Ethyl alcohol converts phosgene to ethyl carbonate. \[CHC{{l}_{3}}+\underset{air}{\mathop{\frac{1}{2}{{O}_{2}}}}\,\xrightarrow{{}}\underset{phosgene}{\mathop{COC{{l}_{2}}}}\,+HCl\] \[COC{{l}_{2}}+2{{C}_{2}}{{H}_{5}}OH\xrightarrow{{}}\underset{ethyl\,\,carbonate}{\mathop{{{({{C}_{2}}{{H}_{5}}O)}_{2}}}}\,+CO+2HCl\]
