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...
Using examples of reagents of your choice, give a detailed
mechanism of a Grignard reaction in organic chemistry.
Please include the formation and stabilization of the ylide,
rate determining step(s), temperature and atmospheric conditions,
catalyst(s), solvent(s), resonance structure(s) of transition
state(s), product(s) etc.
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 ?
