There are four different substituents/groups attached to those atoms, which is why those are both chiral atoms. But, he shows that when the molecule is rotated, it is still the same molecule. That's why even with the chiral ATOMS, the molecule itself is achiral.
WebA chiral space group is a space group whose group structure is chiral: its Euclidean normalizer contains only operations of the first kind. Every chiral type of space group occurs in two enantiomorphic variants. In E 3 there are thus 22 types of chiral space groups, forming 11 enantiomorphic pairs. What is p21 space group?
