Chemistry HELP

Does anyone know how to do any of the multistep syntheses in the photo??

I've already spent two full days trying to do this and I came back to it today thinking maybe I'll do it this time but instead it's just making me want to die.

Please help me. I have four other subjects that I haven't even been able to start yet.
I hate organic synthesis. For 2 and 4 you sort of want to go from an alkane to a carboxylic acid and the only way I think you can do that is through free radical substitution and then reacting that in OH- to form an alcohol and then oxidising that. But for 2 that won't work because you'd end up oxidising the other hydroxyl group. For 4 once you have your carboxylic acid you just need to react it with methanol.

For 2 if you react the haloalkane (with the halogen on the same carbon as OH) with CN- Then react that with H20 and HCl you get your carboxylic acid.

For 3 you want to first oxidise it to a keytone then react it with CN- and then reduce it to form an amine. Then you react it with a carboxylic acid. Pretty mad
Is this right for 2? 14924431386462093932620.jpg
