Consider the acid-catalyzed mechanism of the imine formation (provided in the introduction). How would the reverse reaction proceed? Draw out the mechanism and justify the steps.
2. The price of a bond is generally
determined by
a. the relation between the coupon
rate and the current market rate of similar investments
b. the stated interest rate of the
bond
c. how many bonds are issued
d. who buys the bonds
3. How is the consolidated
statements treatment of constructive gain or loss on intercompany
bond investments different from the treatment of unrealized profit
on intercompany sales of inventory?
a. Constructive gain or loss is
deferred until...
At equilibrium, the rate of the forward reaction is equal to the
rate of the reverse reaction. Both the forward and the reverse
reactions are occurring, but because they are occurring at the same
rate, no change is observed in the appearance of the solution.
For this analysis, think about the affect that the addition or
removal of reactant will have on the rate of the forward reaction
relative to the rate of the reverse reaction at the instant that...
a) Draw the mechanism for nitration of methyl benzoate. Include
formation of the electrophile. The mechanism should explain why the
meta product is obtained.
b) Why is the nitration of aromatic rings a useful reaction?
In
the reaction mechanism of chymotrypsies, formation of the
tetrahedral intermediate is then followed by the formation of an
acyl enzyme Intermediate. What active site residue(s) /are
responsible for forming the first intermediate , and what type of
catalysis occurring the first step of the reaction ?
Given the following reaction, which is the formation of an iron
oxide mineral via hydrolysis:
Fe3+ +3H2O = Fe(OH)3(s) + 3H+
1) Identify the Lewis acids and bases in the above reaction.
2) Define Le Chatelier's principle.
3) Explain how Le Chatelier's principle can be applied to the
above reaction. Specifically, how would increasing the pH of the
reaction change the relative amount of Fe3+ vs Fe(OH)3?
1)
Draw the mechanism and product of: basic hydrolysis of
propanenitrile.
2) Tylenol (acetaminophen) has a much longer shelf life than
aspirin. Explain.
