Chloroform is stored in dark coloured and sealed bottle.Why?

Chloroform is slowly oxidised by air in the presence of light to an extremely poisonous gas, carbonyl chloride, also known as phosgene. It is therefore stored in closed dark coloured bottles completely filled so that air is kept out.

2CHCl​3 + O2 + light  gives 2COCl2 + 2HCl

Chloroform is slowly oxidised by Oxygen present in air in the presence of light to Carbonyl Chloride (Phosgene) - an extremely poisonous gas - by the following reaction, By storing it in closed dark coloured bottles, this is prevented.

@komagal pg308 which book ?? Volume 1 or volume 2 ???
  • -1
Because it get slowly oxidised to an extremly poisonous gas called phosgene

volume 2 chem book

chlorofrom in the presence of air gets oxidised ti phosgene. To prevent the formation of phosegne, Chloroform is stored in dark coloured.
2CHCl3 +O2 ----sunlight------> 2HCl + 2COCl2
