Question

In Bhopal gas tragedy, the gas released was
 A. Methyl isocyanate
 B. Ethyl isocyanate
 C. Sodium isocyanate
 D. Potassium isocyanate

Answer 1

Hint: It is a vapid fluid utilized for making pesticides. MIC is protected when looked after appropriately. The compound is profoundly receptive to warm. At the point when presented to water, the mixes in MIC respond with one another causing a warmth response.

Complete answer:
The Bhopal gas misfortune was a catastrophe that came about because of a mishap. It occurred at a Union Carbide auxiliary pesticide plant in Bhopal, India. On 3 December 1984, the plant delivered 42 tons of harmful methyl isocyanate (MIC) gas, uncovering in excess of 500,000 individuals to poisonous gases. In 1969, the UCIL production line was made to create Sevin (a pesticide) utilizing methyl isocyanate as a halfway. In 1976, worker's guilds in Bhopal griped about contamination inside the plant.
A couple of years after the fact, a specialist coincidentally breathed in a lot of harmful phosgene gas, prompting his passing two or after three hours. Noticing the occasions, a columnist started examining the plant and further distributed his discoveries in Bhopal's neighbourhood paper, saying - 'Wake up individuals of Bhopal, you are on the edge of a spring of gushing lava'. Two years before misfortune struck Bhopal, around 45 laborers who were presented to phosgene were admitted to an emergency clinic. Somewhere in the range of 1983 and 1984, there were breaks of phosgene, carbon tetrachloride, methyl isocyanate and mono methylamine.
Specialists didn't know about legitimate treatment techniques in the episode. Methyl isocyanate gas spill slaughtered in excess of 15,000 individuals and influenced more than 600,000 laborers. The stillbirth rate and the neonatal death rate expanded by up to $300\%$ and $200\%$ individually. The gas spill swayed trees and creatures as well.

So the correct answer is Methyl isocyanate.

Note:
Methyl Isocyanate is not, at this point underway, in spite of the fact that it is as yet utilized in pesticides. The Bayer Crop Science plant in Institute, West Virginia is right now the solitary stockpiling area of MIC left across the globe. Inside two or three days, trees in the close by region got infertile. Enlarged creature remains must be discarded. Individuals ran in the city, heaving and passing on. The city ran out of incineration grounds.
