(a)
Interpretation:
An equation for the reaction that took place in the tank of methyl isocyanate with water (Bhopal gas accident) and an explanation for the rose in pressure and temperature dramatically are to be stated.
Concept introduction:
At
(b)
Interpretation:
A mechanism for the reaction that took place in the tank of methyl isocyanate with water in the Bhopal gas accident is to be stated.
Concept introduction:
A mechanism of the reaction between methyl isocyanate and water comprises two steps. The first step is nucleophilic attack of water molecule on the carbonyl carbon followed by formation of an acid. The second step is cleavage of the bond between carbonyl carbon and nitrogen by deprotonation of acid and protonation of
(c)
Interpretation:
An alternative synthesis of Sevin is to be stated.
Concept introduction:
Diethyl carbonate is an ester (prepared from carbonic acid and ethanol). It is a liquid reagent that is easy to handle. However, phosgene is a corrosive and highly toxic. Diethyl carbonate successfully replaces phosgene in the synthesis of Lexan and Sevin.

- The reaction of p-cresol with CH2=O resembles the reaction of phenol (PhOH) with CH2=O, except that the resulting polymer is thermoplastic but not thermosetting. Draw the structure of the polymer formed, and explain why the properties of these two polymers are so different.arrow_forwardIn the final product, triphenylmethyl ethyl ether, there is only one oxygen atom. From which of the two starting materials did it come?arrow_forwardThis triene reacts with excess maleic anhydride to produce a compound with molecular formula C14,H12,O6.

- Compound A, C 10H 18O, undergoes reaction with dilute H 2SO 4 at 50 °C to yield a mixture of two alkenes, C 10H 16. The major alkene B, gives only cyclopentanone after ozone treatment followed by reduction with zinc in acetic acid. Which of the following reactions are correct. Can be more than one answerarrow_forwardA graduate student was studying enzymatic reductions of cyclohexanones when she encountered some interesting chemistry. When she used an enzyme and NADPH to reduce the following ketone, she was surprised to find that the product was optically active. She carefully repurified the product so that no enzyme, NADPH, or other contaminants were present. Still, the product was optically active. If this reaction could be accomplished using H2 and a nickel catalyst, would the product be optically active? Explain.arrow_forwardNitromethane is reacted with ethyl prop-2-enoate with EtO-Na+, EtOH 3 equivalents to give the product X(C16). X then reacts with H2/Raney Ni to give the product Y(C14), which in turn reacts with Na to give Z (C12). Indicate which products X, Y and Z are.arrow_forward
