Draw the product of feature action including stereochemistry.
00:03
All right, so let's take a look at a.
00:05
So we've got an alken and we've got br2.
00:08
When br2 and alkener are going to interact, we're going to have alkin will donate electron to the br, br will donate back, and the br will donate electrons to the other br.
00:18
So we end up with this pretty cool looking thing where the br is going to bond to both carbons at the same time, and he's going to be in the front.
00:30
Because it's too many bonds, he's positive.
00:33
We also have that other br, which is negative.
00:37
Now, this br, because he's negative, is going to attempt to make a new bond.
00:42
And this br, because he's positive, is going to attempt to lose a bond.
00:45
So in this case, it looks like it's the same either way.
00:48
We can go top or bottom.
00:49
But let's say the top one is going to donate to the br, while this br is going to come and attack that same carbon.
00:59
So we have a backside attack here.
01:01
So what backside attack means that what was in the front is not going to be the back.
01:05
The back is giving the front.
01:08
So br attached to the bottom, unaffected...
