Options

A. `CH_(2)CN`
B. `CH_(3)NC`
C. `CH_(3)N=C=O`
D. `CH_(3)-N=O`

Answer

**Step-by-Step Solution:**

1. **Identify the Incident**: The Bhopal gas tragedy occurred on the night of December 2, 1984, in Bhopal, India. It is recognized as one of the world's worst industrial disasters.

3. **Identify the Toxic Gas**: The primary gas responsible for the tragedy was methyl isocyanate (MIC), which has the chemical formula CH3NCO.

4. **Chemical Reaction**: The disaster was triggered when water accidentally entered a storage tank containing methyl isocyanate. This led to a violent chemical reaction.

5. **Consequences of the Reaction**: The reaction resulted in the production of several toxic gases, including carbon dioxide and others, which then leaked into the atmosphere.

6. **Impact on Human Life**: The toxic gases spread rapidly, leading to severe health impacts and fatalities among the local population who inhaled the gases.

7. **Conclusion**: Therefore, the gas responsible for the Bhopal gas tragedy is methyl isocyanate (CH3NCO).

**Final Answer**: The Bhopal gas tragedy was caused by methyl isocyanate (CH3NCO).
