Textbook Question
Chapter H, Problem 5PP
Practice Problem H.5
Many alkaloids appear to be synthesized in plants by reactions that resemble the Mannich reaction (Section 19.8). Recognition of this (by R. Robinson in 1917) led to a synthesis of tropinone that takes place under “physiological conditions,” that is, at room temperature and at pH values near neutrality. This synthesis is shown here (and discussed in “Why These Topics Matter” at the end of Chapter 19). Propose reasonable mechanisms that account for the overall course of the reaction.

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
2NO2 (g) = N2O4(g)
AGº = -5.4 kJ
Now suppose a reaction vessel is filled with 4.53 atm of dinitrogen tetroxide (N2O4) at 279. °C. Answer the following questions about this system:
Under these conditions, will the pressure of N2O4 tend to rise or fall?
Is it possible to reverse this tendency by adding NO2?
In other words, if you said the pressure of N2O4 will tend to rise, can that
be changed to a tendency to fall by adding NO2? Similarly, if you said the
pressure of N2O4 will tend to fall, can that be changed to a tendency to
'2'
rise by adding NO2?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of NO 2 needed to reverse it.
Round your answer to 2 significant digits.
