Hydrohalogenation of alkynes- Part 1
This video talks about the mechanism involved when a symmetrical alkyne is treated with a hydrogen halide.
00:00- Introduction
1:03-Reaction between ethyne and HBr
1:44- Why is there no resonance in case of a vinylic carbocation?
3:40- What happens if we have excess HBr?
4:42- How do we decide the major product?
