Which of the following gases is formed during oxidation of trichloromethane?
Which of the following gases is formed during oxidation of trichloromethane?
$\mathrm{CO}_{(\mathrm{g})}$
$\mathrm{CO}_{2(\mathrm{~g})}$
$\mathrm{COCl}_{2(\mathrm{~g})}$
$\mathrm{H}_{2(\mathrm{~g})}$
Solution
Chloroform (trichloromethane) when exposed to air and light forms a poisonous compound phosgene $\left(\mathrm{COCl}_2\right)$ so it is stored in dark coloured air tight bottles.
