sorry i don't about making 4 threads, the other 3 aren't working for some reason. my post doesn't show up 😕
We just started doing this and it's REALLY confusing me. I spent a lot of time learning preparation for alkynes, reductions, hydroborations, etc and now it's like I have to apply all that for the synthesis problems and I'm not getting it. I don't understand how when given a target molecule and the starting materials (acetylene and a haloalkane) how you know which steps to do in order to eventually get to the target molecule.
Example, if you have a target molecule of cis-3-Hexene and have starting materials of Acetylene and Bromoethane.
How do you know that you are supposed to do it in 5 steps like this?
1. NaNH2 ----> 2. CH3CH2Br
1-Butyne
3. NaNH2 ----> 4. CH3CH2Br
3-Hexyne
5. H2 ----> Lindlar catalyst
target molecule: cis-3-Hexene
Have an exam on Thurs, I seem to understand everything but this 🙁
