The Attempt at a Solution

I have no idea how to attempt this problem set. The instructor had this insane idea that if he gave us questions that we've never seen/dealt with before that he'd be doing a better job. problem is that nobody knows how to attempt these questions. I'm not trying to get anyone to do my problems for me, but can u guys give me hints on how to attempt each question? I'm really puzzled and lost.

thank you for your help

1) What is the product formed when the protein is reacted with the 2,4-dinitrofluorobenzene? What would happen if that product were hydrolyzed with HCl? What would you see? There is a slight error in the problem. The individual amino acids shown after hydrolysis show the group HN- instead of the correct H2N- funtionality.

2) Approach this problem by doing a retrosynthetic analysis. What do you think the last reaction was to form this product? What were the reactants for that transformation and how were they formed?

3) Again do a retrosynthetic analysis. The product has the same number of carbons as the starting material but no double bond and two hydroxyls. What transformation(s) do you know that convert double bonds to diols? What process(es) will cause the scission of the carbon bond and produce diols?

4) Do you understand the reagents employed? (PCC, DMS, O3, CF3CO3H, etc...)

As a fellow scientist, I understand the frustration and confusion you may be feeling when faced with new and challenging problems. However, I believe that your instructor's approach may have a purpose behind it - to push you to think critically and independently. Organic chemistry is a subject that requires a lot of practice and problem-solving skills. Here are some general tips that may help you approach these questions:

1. Start by understanding the question: Read the question carefully and make sure you understand what is being asked. Pay attention to key words and phrases, and try to break down the question into smaller parts.

2. Review your notes and textbook: Before attempting the questions, review the relevant material from your class notes and textbook. This will help refresh your memory and provide you with the necessary background knowledge.

3. Identify the key concepts: Identify the main concepts and principles that are relevant to the question. This will help you focus your thinking and approach the problem more systematically.

4. Draw diagrams and structures: Organic chemistry problems often involve drawing molecules and structures. Make sure you have a clear understanding of how to draw these and use them to help you visualize the problem.

5. Work through examples: If your textbook or notes have examples of similar problems, work through them first to get a better understanding of the concepts and techniques involved.

6. Use problem-solving strategies: There are many problem-solving strategies you can use, such as working backwards, making a table, or using trial and error. Find the strategy that works best for you and apply it to the problem.

7. Don't be afraid to ask for help: If you're still stuck, don't hesitate to ask your instructor or classmates for help. Sometimes discussing the problem with others can help you see it from a different perspective and find a solution.

Remember, it's normal to feel puzzled and lost when faced with new and challenging problems. But with practice and perseverance, you can develop the necessary skills to tackle them successfully. Good luck!
