Which poisonous gas leaked in the Bhopal gas tragedy of December 1984?
Answer and explanation
Correct answer A
The gas was methyl isocyanate (CH3NCO). On the night of 2–3 December 1984 about 40 tonnes of it escaped from a storage tank at the Union Carbide pesticide plant in Bhopal after water entered the tank and set off a runaway reaction; methyl isocyanate was an intermediate in making the pesticide carbaryl. Antimony hydride (stibine), nitrogen oxides and acetyl fluoride are toxic too, but none of them was the gas released at Bhopal.
