00:01
Okay, first up we have alanine.
00:05
Very simple amino acid.
00:09
And the three -dimensionalness is that we have a wedge to our nh2, our amine group.
00:19
And there's a methyl group here.
00:21
So this would be aline and its mirror image then.
00:35
If we really want it to be strict about the whole mirror image thing, we could put the h2 over here, i guess.
00:43
Okay.
00:43
Okay, so are these an anemeter's or the same molecule? well, we notice that we do have a stereo center here, which we should star.
00:52
And since we have a stereo center, we know that the mirror image must be in an ant tumor.
01:00
Okay, let's continue.
01:02
Next, we've got one bromide, two methyl butane.
01:06
It's a butane, one bromo, and two methyl.
01:15
So it would appear that we have a stereo center, right? for example, on this carbon, we have a methyl group, a hydrogen, an ethyl group, and a methyl bromide.
01:30
So it would be necessary here to indicate whether we have r or s stereo center.
01:38
So we can just make this one as follows.
01:44
Okay.
01:46
And so this becomes a stereo center and our mirror image then would also have a stereo center and these two would be any endemers.
02:03
One being the r and one being the s.
02:08
Next we have chloro cyclohexane...
