We want to draw three isomers of trans 1 -2 dichlorocycloseucidate and label them as either constitutional or stereo isomers.
00:12
So i went ahead and put the definitions of each above here.
00:17
Now, a quick one to get is if we were to just turn this from trans to cis.
00:25
So this is going to give a stereo isomer of it because the c.
00:31
Of the atoms are not going to change, but if we were to look at this in three -dimensional space, then it's going to look different.
00:44
So let's go ahead and draw that.
00:46
So cyclobutane, so i always have to say mike eats peanut butter.
00:52
And so butane is going to be the fourth one in that because of the b.
00:57
So that is going to give us a four -membered range.
01:04
Then at positions 1 in positions 2, we're going to have chlorines.
01:08
So we have chlorine here, chlorine here.
01:11
And since it's cis, we just go ahead and make sure these are on the same side.
01:18
So that's going to be one of the stereo isomers of this.
01:22
Now we can go ahead and get some constitutional isomers by moving the chlorines around.
01:32
So first, let's go ahead and take this.
01:36
Chlorine and move it to be on the same carbon as our first one.
01:41
So that's going to give us.
01:43
So we have two chlorines on here.
01:46
So you could go ahead and put the wedge and dash, but it's not really going to matter.
01:53
So that's one of our constitutional isomers...
