How do you synthesize ethyne from ethane?
If ethane reacts with Br2/hv you get Ch3Ch2Br. Where can you go from here?

you need to make a vicinal dihalide (1,2-dibromoethane) and react it with excess Sodium Hydroxide at 200°C
You need to hit it with Br2. Then either fused KOH at 200 degrees or NaNH2 at 150 degrees. NaNH2 at 150 gives terminal alkynes while KOH at 200 gives internal alkynes. I got an A- in orgo I at a top 20 school for what its worth. Best of luck in orgo II!
it is not a problem today to find the correct synthesis aim. Anyway, if the question is about the chemical custom synthesis, the best result of it for me is https://ereztech.com/product/trimethyl-phosphite-121-45-9/ aimed to keep my screen clean all the time long. I'll happily work further with them and keep it as it is.
