Ethyl alcohol................... is the answer.......
zaisha58:
can u plzz explain tge concept behind this
plzzzzzzz
Chloroform forms a very poisonous compound called phosgene ( COCl2) when stored for a long time by reacting with oxygen in presence of sunlight.
CHCl3 + 1/2 O2 →COCl2 + HCl
In order to consume that phosgene gas and make chloroform safe, it is mixed with ethanol.
OCCl2 + 2 HOC2H5→ O=C(OC2H5)2 + 2 HCl
CHCl3 + 1/2 O2 →COCl2 + HCl
In order to consume that phosgene gas and make chloroform safe, it is mixed with ethanol.
OCCl2 + 2 HOC2H5→ O=C(OC2H5)2 + 2 HCl
thanku soooo much khushi
welcome.... dear
happy new yr

Option B is correct.
Ethyl Alcohol is used to as a negative catalyst for the aerial oxidation of chorform to slow down its aerial oxidation in presence of light.
Chloroform vapor slowly reacts with oxygen in the presence of light to generate phosgene, a highly toxic gas.
2CHCl3(l) + O2 (g) -----> 2COCl2(g) + 2HCl(g)
