Answer 2

Ethyl alcohol is used as a preservative for chloroform

because:

- It removes phosgene by converting it into ethyl carbonate

- Chloroform gets oxidised slowly by air in the presence of light to poisonous phosgene gas.

2CHCl3 + O2 ------> 2COCl2 + 2HCl

- Ethyl alcohol is used to remove this poisonous phosgene gas by converting it into ethyl carbonate

COCl₂+ 2C₂H₅OH——> (C₂H₅)₂CO₃+ 2HCl

So, the correct option is (d)
