The correct answer is D. Methyl isocyanate.
Methyl isocyanate (MIC) is a highly toxic gas that was released from the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, India on December 2, 1984. The release of MIC killed an estimated 22,500 people and injured over 500,000 others. It is considered one of the worst industrial disasters in history.
MIC is a colorless, flammable liquid with a strong, irritating odor. It is used in the production of pesticides, herbicides, and other chemicals. It is also used in the manufacture of polyurethane foams and plastics.
MIC is a highly toxic gas that can cause death if inhaled. It can also cause skin and eye irritation, and respiratory problems. If ingested, MIC can cause nausea, vomiting, diarrhea, and seizures.
The Bhopal disaster was caused by a combination of human error and design flaws at the UCIL plant. The plant was not properly maintained, and there were no safety measures in place to prevent the release of MIC. As a result, when a water leak occurred in one of the plant’s storage tanks, it caused a chemical reaction that released a cloud of MIC into the atmosphere.
The Bhopal disaster had a devastating impact on the people of Bhopal. Thousands of people were killed or injured, and many more were left with long-term health problems. The disaster also caused widespread environmental damage.
The Bhopal disaster is a reminder of the dangers of industrial pollution and the importance of safety measures in chemical plants. It is also a reminder of the need for companies to be held accountable for their actions.
The other options are incorrect because they are not toxic gases. Sodium isothiocyanate is a white, crystalline solid that is used in the production of dyes and pharmaceuticals. Potassium isothiocyanate is
a white, crystalline solid that is used in the production of pesticides and herbicides. Ethyl isothiocyanate is a colorless, flammable liquid that is used in the production of pharmaceuticals and pesticides.
