Bhopal gas tragedy of 1884 took place because methyl isocyanate reacted with:
ADDT
BAmmonia
CCO2
DWater
Answer:
D. Water
Read Explanation:
- The Bhopal gas tragedy, one of the world's most devastating industrial disasters, took place during the early hours of December 3, 1984, at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, India.
- The tragedy resulted from the release of methyl isocyanate (MIC) gas, a highly toxic compound used in the production of pesticides like carbaryl.
- MIC was one of the intermediate chemicals used in the production process at the plant.
- It was stored in large tanks.
- Due to a combination of factors including poor maintenance, lack of safety measures, and systemic failures, water entered the storage tank where MIC was kept.
- The water triggered a runaway reaction with MIC.
- When water entered the tank containing MIC, it caused an exothermic (heat-producing) reaction.
- This reaction led to a rapid increase in temperature and pressure within the storage tank.
- As the temperature and pressure increased, the storage tank's safety systems failed to contain the reaction.
- Eventually, a large amount of highly toxic MIC gas was released into the surrounding atmosphere.
