A) chloral
B) acetyl chloride
C) phosgene
D) methyl chloride
Correct Answer: C
Solution :
Chloroform on exposure to sunlight in presence of air forms phosgene, a deadly poisnous gas. To avoid this oxidation, \[CHC{{l}_{3}}\]is always stored in dark bottles and filled up till the brim so as to expel all the air out of the bottle. Small amount of ethanol is also added to it which act as a negative catalyst by retarding the rate of conversion of \[CHC{{l}_{3}}\]to phosgene \[2CHC{{l}_{3}}+{{O}_{2}}\,\xrightarrow{hv}\underset{\begin{smallmatrix} Carbonyl\,chloride \\ or\,phosgene \end{smallmatrix}}{\mathop{2COC{{l}_{2}}}}\,+2HCl\]You need to login to perform this action.
