So the mechanism of this reaction, we're starting with an alkyne, carbon, carbon, triple bond.
00:06
This is reacting with bromine.
00:07
So brbr.
00:09
First step here is react with the bromine.
00:15
And this would come out.
00:17
And we'd lose a bromine here.
00:20
So this would give us double bond.
00:32
Going out of the page, bromine.
00:38
Then this br minus left hanging around.
00:42
Would attack here.
00:46
This would come out.
00:48
And then their next step, this would give us br...
