Question

Name the gas released during Bhopal tragedy in 1984.

Answer 1

• The Bhopal disaster, also referred to as the Bhopal gas tragedy, was a gas leak incident on the night of 2nd–3rd December, 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India.
• The highly toxic substance made its way into and around the small towns located near the plant.
• The UCIL factory was built in 1969 to produce the pesticide Sevin (UCC's brand name for carbaryl) using methyl isocyanate (MIC) as an intermediate.
• The chemical process employed in the Bhopal plant had methylamine reacting with phosgene to form MIC, which was then reacted with 1-naphthol to form the final product, carbaryl.

So the correct option is 'methyl isocyanate'.
