(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.

- When aniline, C6H5NH2(Kb=7.41010) , reacts with a strong acid, its conjugate acid, C6H5NH3+, is formed.

Calculate the equilibrium constant for the reaction. If 0.10 M solutions of these two species are mixed, what will be their concentrations at equilibrium?arrow_forwardIn a time-resolved picosecond spectroscopy experiment, Sheps, Crowther, Carrier, and Crim (Journal of Physical Chemistry A, Vol. 110, 2006; pp. 30873092) generated chlorine atoms in the presence of pentane. The pentane was dissolved in dichloromethane, CH2C12. The chlorine atoms are free radicals and are very reactive. After a nanosecond the chlorine atoms have reacted with pentane molecules, removing a hydrogen atom to form HCl and leaving behind a pentane radical with a single unpaired electron. The equation is Cl (dcm) + C5H12(dcm) HCl(dcm) + C5H11 (dcm) where (dcm) indicates that a substance is dissolved in dichloromethane. Measurements of the concentration of chlorine atoms were made as a function of time at three different concentrations of pentane in the dichloromethane. These results are shown in the table. (a) Determine the order of the reaction with respect to chlorine. (b) Determine whether the reaction rate depends on the concentration of pentane in dichloromethane. If so, determine the order of the reaction with respect to pentane. (c) Explain why the concentration of pentane in dichloromethane does not affect the data analysis that you performed in part (a). (d) Write the rate law for the reaction and calculate the rate of reaction for a concentration of chlorine atoms equal to 1.0 M and a pentane concentration of 0.23 M. (e) Sheps, Crowther, Carrier, and Crim found that the rate of formation of HCl matched the rate of disappearance of Cl. From this they concluded that there were no intermediates and side reactions were not important. Explain the basis for this conclusion.arrow_forward

Nylon 6 and poly(ε-caprolactone) have similar polymer backbone structure with one carbonyl, 5 methylene and a heteroatom, nitrogen or oxygen, respectively. Each is able to undergo crystallization. However, their thermal transition temperature differs significantly. The glass transition temperature (Tg) for Nylon 6 is 52 °C, whereas the Tg for poly(εcaprolactone) is 112 degree lower than Nylon 6 at – 60 °C. Similarly, the melting temperature (Tm) for Nylon 6 is 223 °C, whereas the Tm for poly(εcaprolactone) is 60 °C.

Zinc (Zn) granules react slowly with dilute hydrochloric acid (HCI), but much faster if the acid is concentrated. Zn(s) 2HCI(aq)ZnCl2(aq) + H2(g) Zinc + Hydrochloric Acid Zinc Chloride + Hydrogen What causes the reaction to proceed faster with concentrated acid? The concentrated hydrochloric acid causes more hydrogen gas to be produced. The pressure of hydrogen gas molecules increases as concentration increases. The concentrated hydrochloric acid molecules move faster than in dilute acid. There are more collisions between the zinc and concentrated hydrochloric acid. PREVIOUarrow_forward
