Hey guys, so in this question, we're asked to define chiral and define what an antimer is.
00:08
So chiral means that a molecule is non -superimposable on its mirror image.
00:16
Where non -superimposable means that it can't be placed on top of its mirror image and still be the same molecule.
00:24
So just a simple picture of chirality, we have, say, we have, say, we have, have this compound where we have carbon right here and then it has some attachments so let's say it has four attachments two that are in the plane one that it's out of the page and what's one that's into the page where this one's going to be blue this one will be red this one will be green and this one will be black.
01:08
If we also have a mirror here and place this in the mirror, its reflection will look like this, where we have this bond facing this bond, this bond is in the same place as this bond, and this back bond is facing this way.
01:34
And when we place our molecules here, we have our green molecule here, the blue one is here, red is here, and black is here.
01:48
We see this.
01:49
We see this, that if we try to flip this mirror image onto this molecule, they will not stack.
01:56
So these are non -superimposable mirror images, meaning that this carbon is chiral.
02:04
So what's an anemir then? and an antiumer is a type of stereo isomer that is non -superimposable on its mirror image...
