WebThe presence of a single chirality centre in a molecule results in a chiral molecule fundamentally because the top, bottom, left, right, front and back faces are all different. … WebBut if I think about over here, I have a chiral center at this carbon, and that's going to affect these two protons. These two protons are no longer chemically equivalent, alright, because a chiral center is present. So in general, if a chiral center is present, the two protons on a methylene group, on a CH2 group, are generally not equivalent.

WebAnswer (1 of 3): Yes, there are some classes of molecules that are chiral. The first approach to understand it is to know that an molecule (or any object, in fact) is chiral if it is not superimposable to itself. This said, what remains to be seen what produces this. And this comes to happens i...
