You will apply the oxidation reaction to 9-fluorenol to obtain 9-fluorenone:

1. Describe the role of each chemical in this reaction.

Reagent	Role
9-fluorenol
H₂CrO₄
acetone
ether
hexanes

2. What is the actual oxidizing agent in this experiment? What is it reduced to?

3.After all of the 9-flurenol has undergone reaction, it is necessary to destroy the excess oxidizing agent in the reaction mixture. How is this done?

4. Imagine that you will monitor the reaction progress by TLC. Will the product be the higher or lower spot? What is the significant difference between 9-fluorenone and 9-fluorenol that allows reaction progress to be monitored by TLC?

Expert Solution

1. Role of each chemical in the oxidation of 9-fluorenol to 9-fluorenone

Reagent Role

9-fluorenol Substrate/starting material

H2CrO4 Oxidant

acetone Solvent

ether solvent

hexane Extracting solvent

2. Actual oxidizing agent in the reaction is the chromic acid in Cr(VI) oxidization state. It is reduced to Cr(III) state.

3. It is necessary to destroy the excess oxidizing agent present in the reaction mixture once the reaction is complete. This is done by adding i-PrOH to the reaction mixture.

4. The reaction If monitored by tlc, will have substrate lower than the product. Alcohol is more polar than the ketone product and would stick behind on the plate.

1) You obtain the sequence of a gene containing 10 exons, 9 introns, and a 3′ UTR containing a polyadenylation consensus sequence. The fifth intron also contains a polyadenylation site. To test whether both polyadenylation sites are used, you isolate mRNA and find a longer transcript from muscle tissue and a shorter transcript from all other tissues. Briefly speculate about the mechanism involved in the production of these different transcripts. 2) Briefly speculate about why plants deficient in Dicer activity...

1) Using the half-reaction method, balance the following oxidation-reduction reaction which occurs in acidic solution. Be sure to show each step in balancing both half-reactions and how electrons in each half reaction are balanced. Mn2+ (aq) + IO4– (aq) → MnO4– (aq) + IO3– (aq) 2) Would you expect ions such as Cu2+ (light blue solutions) and Ni2+ (light green solutions) to interfere in the analysis of MnO4–? Why or why not? 3)Explain quantitatively how your value for the percent...
