All right, so starting with drawing all the isomers of the autotetros from the last problem, in their 3d confirmations, we're going to start just by drawing first the aldehyde.
00:12
And now we can start drawing the rest of the bomb.
00:15
So in a normal fissure projection, the bonds kind of down the middle are on these wedges, so we can have carbon with dashes coming out to the sides like this.
00:35
And this is going to be the first isomer.
00:42
Of this molecule.
00:47
On a similar note, we can start drawing the second isomer.
00:56
Note that there are four of these isomers total, by first drawing a disteriumer of this first molecule.
01:08
We can do that by just flipping one of the chirocenters.
01:13
So instead of having an oh -h on this side, this time we can draw an h.
01:28
So next we can draw a different disteriomer, this time having the oh -h on this side.
01:47
While keeping the oh on this side here.
02:03
And lastly, we can draw the an itimer, in other words, the complete mirror image.
02:24
All right...
