I'm a bit confused on enantiomers, diastereomers, and then a 180 flip meaning being "the same". I know enantiomers are mirror images that can't be placed one on top of the other. I also know diastereomers are non-mirror images. Then when diastereomers are flipped 180 degrees they can be considered "the same". Why couldn't that be said for enantiomers too when flipped 180 degrees? Thank you!

12. Consider the molecule shown below. ОН ОН f. How many stereoisomers are possible? g. Draw each of these stereoisomers. h. Identify pairs of enantiomers and pairs of diastereomers. i. Build a model of the stereoisomer that has both OH groups pointing out. Also, build a model of the mirror image of this molecule. j. Do your two molecules represent enantiomers? Are they chiral?
chiral. If you were able to make another molecule that is a mirror image of the chiral molecule, the mirror image and the original molecule will be non-superimposable. i.e. the atoms surrounding carbon won't completely align. The lack of alignment of the suround atom makes the two molecules different from each other. The central carbon must be surrounded by 4 different groups. The chiral carbon is highlighted.
