Please help me with a few synthesis problems

[asdfTT123]

I've been staring at these for a while now and I can't seem to get them. I would really appreciate anyone's help with these.

1. Methylcyclohexane -> 1-methyl,2-bromo-cyclohexane (bromine added to ortho carbon in respect to the methyl group). The main problem here is that I don't know where to start!

2, 3. The rest are on the attachment.

Thanks!

Sorry...I realized this was the wrong forum for this.

I would be happy to assist you with these synthesis problems. To begin with, for the first problem, you can start by identifying the functional group and the carbon that needs to be brominated. In this case, the functional group is a methyl group and the carbon that needs to be brominated is the one adjacent to it, also known as the ortho carbon. To add a bromine to this specific carbon, you will need to use a reagent called N-bromosuccinimide (NBS) in the presence of light or heat. This reaction is known as a radical halogenation. Once the bromine is added, you will have 1-methyl,2-bromo-cyclohexane as the final product.

For the remaining synthesis problems, it would be helpful if you could provide the attachment so I can have a better understanding of the specific molecules and reactions involved. Each synthesis problem requires a different approach and it would be difficult to provide a general response without knowing the specific details. However, some general tips for approaching synthesis problems include identifying the starting material, functional groups, and reagents involved, as well as considering any potential side reactions or competing pathways.

I hope this helps and I am looking forward to seeing the attachment for the remaining problems. Good luck!
