Okay, so we're starting with this halthahide, reacting with ethyl -grenured, and then protonating.
00:20
The first case, this ethyl is just going to add once, but it can attack from either side.
00:27
So if it were to attack from the front -hand side, we'll have the ethyl here, the methyl on the back, alcohol up, and the hydrogen on the right -hand side.
00:39
But the ethyl could also attack from the back and generate, it's actually redraw that, the ethyl could attack from the back, generate the enantiomer.
01:00
So these would be the two products that you'd get.
01:05
In the second case, we're starting off with this compound.
01:12
This methyl could be either up or down, and it would be the same product because this is miso...
