also chiral stationary phase reacts with both enantiomers, but with a different strenght of binding. Guy who is stronger interacting will come later, guy who is weaker interacting will come first, I think there is over statement in your video, nevertheless pretty good
Wouldnt the molecules at the beginning of the video be diastereomers not enatiomers because the configuration of one of their chiral centers is different?
recall: diastereomers are not superimposable and not mirror images of each other. Enantiomers on the other hand are not superimposable; however, they are mirror images of each other. I think what you are mistaking with is what is called an epimer, where one chiral center differs in both molecules; however, epimers are a type of diastereomer and not an enantiomer of eachother. if you imagine putting one of the molecule in the beginning of the video in front of a mirror we would obtain the other molecule.
what do you mean by test? If you want to check whether or not it is racemic (equal parts L and R), you can measure it's optical activity (whether or not it rotates polarized light)
Thanks
I love you! This is going to help me on my orgo I exam :)

In this example, is the chiral stationary phase R?
thanks very much!!
plz explain the apparatus in the experiment......
What program is used to produce the drawing in concert with the discussion?

Not S or R conformation, configuration is the proper word
Right
so there'S no easy way I can test my L-ascorbic acid without chiral stationary phase? That's what I thought
