Question

Assertion: Methyl isocyanide reacts with ozone to form methyl isocyanate.
Reason: Methyl isocyanate was responsible for Bhopal tragedy.
A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C. Assertion is correct but Reason is incorrect.
D. Both Assertion and Reason are incorrect.

Answer 1

We need to remember that an organic compound and member of isocyanide group is methyl isocyanide. It is colorless liquid and is isomeric to acetonitrile. 5-Membered heterocyclic rings could be prepared using methyl isocyanide. Methyl isocyanide is prepared by dehydration of N-methylformamide.

Complete step by step answer:
We must need to know that the other name of methyl isocyanide is iso cyanomethane. Methyl isocyanate is formed from the reaction of methyl isocyanide and ozone. The chemical formula of methyl isocyanate is $C{H_3}NCO$ . The IUPAC name of methyl isocyanate is isocyanatomethane. We need to know that the methyl isocyanate is a poisonous, colorless, flammable liquid. Methyl isocyanate could be manufactured using monomethylamine and phosgene.Methyl isocyanate is intermediate in the creation of carbamate pesticides, (for example, carbaryl, carbofuran, methomyl, and aldicarb). It has likewise been utilized in the formation of rubbers and glues. As a profoundly poisonous and bothering material, it is incredibly dangerous to human wellbeing. It was the vital poison associated with the Bhopal disaster.
We must have to know that the methyl isocyanide on reaction with ozone forms the product methyl isocyanate, the assertion is correct whereas the reason is not correct explanation of assertion because the terminal atom of carbon found in isocyanide contains carbon that is electron-deficient comprising sextet of carbon and thus, goes addition reactions with ozone.

So, the correct answer is Option B.

Note: We have to know that Methyl isocyanate is incredibly harmful. The harmful impact of the compound was evident in the $1984$ Bhopal calamity, when around $42,000$ kilograms (93,000 lb) of methyl isocyanate and different gases were delivered from the underground supplies of the Union Carbide India Limited (UCIL) Higher degrees of introduction, more than $21ppm$ , can bring about respiratory or lung edema, emphysema and hemorrhages, bronchial pneumonia and demise.
