Chapter 20, Problem 52P

When phenyl isochiocyanatc, C 6 H 5 N = C = S , is reduced with lithium aluminum hydride, the product formed has these spectral data:

MS ( m/z ) : 107, 106

IR ( c m 1 ) : 3330(sharp), 3050, 2815, 760,700

1 H NMR ( δ ) : 2.7 ( s ,   3 H ) ,   3.5   ( b r o a d ,   1 H ) ,   6.6   ( δ ,   2 H ) ,   6.7   ( t ,   1 H )   7.2   ( t ,   2 H )

1 3 C NMR ( δ ) : 30   ( C H 3 ) ,   112 ( C H ) ,   117 ( C H ) ,   129 ( C H ) ,   150 ( C )

(a) What is the structure of the product?

(b) What is the structure that accounts for the 106 m/z peak and how is it formed? (It is an iminium ion.)

The data for the potential difference of a battery and its temperature are given in the table. Calculate the entropy change in J mol-1 K-1 (indicate the formulas used).Data: F = 96485 C mol-1
In a cell, the change in entropy (AS) can be calculated from the slope of the E° vs 1/T graph. The slope is equal to -AS/R, where R is the gas constant. Is this correct?
Using the Arrhenius equation, it is possible to establish the relationship between the rate constant (k) of a chemical reaction and the temperature (T), in Kelvin (K), the universal gas constant (R), the pre-exponential factor (A) and the activation energy (Ea). This equation is widely applied in studies of chemical kinetics, and is also widely used to determine the activation energy of reactions. In this context, the following graph shows the variation of the rate constant with the inverse of the absolute temperature, for a given chemical reaction that obeys the Arrhenius equation. Based on the analysis of this graph and the concepts acquired about the kinetics of chemical reactions, analyze the following statements:              I. The activation energy (Ea) varies with the temperature of the system.   II. The activation energy (Ea) varies with the concentration of the reactants.        III. The rate constant (K) varies proportionally with temperature.    IV. The value of the…
