Organic Chemistry Help please!

[stressed123]

Hi everyone. I'm going to apologize in advance for any rules I've broken. So I really need help with these problems - I am willing to pay for answers to these as well. But I guess with any forum - if you ask for help, you'll have to at least make an attempt as well.

 

These questions are actually from an exam I sat recently (and failed....) I have to resit the exam next Wednesday (may or may not be different) so any help is greatly appreciated.

 

So the questions I'm having problems with are 1, 2, 3, 4, 5, 10

 

Here are my attempts:

 

1. IUPAC name - benzyl amine

 

2. I really don't have a clue with this one - need to do a bit more study.

 

3. Will need to do a bit more study - but will post my attempts

 

4. Product 1 --> would be the cyclic bonds broken - so it would be a long chain with alcohols attached

Product 2--> LiAlH4 is used as a reducing agent

 

5. in the exam i had no clue what to do here...

 

10. I actually only received 4.5/24 marks for this question so I really have no clue where to start. I guess it's better than a few other questions where I got 0... But I only really had problems with parts C and D for this.

 

Thank you so much in advance!!!

[hypervalent_iodine]

1. That's the name that is commonly used, but it's not the IUPAC name.

 

2. Is it high spin or low spin? How many unpaired electrons does the iron have? Magnetic moment?

 

3. Will wait for your attempts.

 

4. You're missing the other functional group. What is the functional group present in the starting molecule? What are the structures of the products? Yes, LiAlH4 is a reducing agent, but that isn't an answer. What about 3?

 

5. Break it down. What functional groups do you have and what do the reagents do to those groups?

 

10. What were your answers?

Here are some of my attempts

[hypervalent_iodine]

1. Why does the NH3 turn into an NH2- in your first step? That doesn't make sense. Neither does the next step.

 

2. Do you have to calculate the magnetic moment?

 

3. No. The halogens won't coordinate like that. You have another atom in there that can coordinate.

 

4. a. Yes. b. Close. If you have two of the one type of group, you have to specify that by adding a di- prefix. d. Yes.

1. I'll redo this one.

2. That should probably be enough I hope!

3. Not too sure about this one..

4. Good to know that it's right !

 

Here is my attempt at question 5 (what I could do)

Here is my attempt at question 10
