I love you! This is going to help me on my orgo I exam :)

@kachingchan9228 9 лет назад

thanks very much!!

@avirajsarkar5846 10 лет назад

plz explain the apparatus in the experiment......

@wrednykocurek 3 года назад

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

@pharmedutainment 7 лет назад

What program is used to produce the drawing in concert with the discussion?

@banglavlogabroad Месяц назад

In this example, is the chiral stationary phase R?

@taylorclarke2550 5 лет назад

Wouldnt the molecules at the beginning of the video be diastereomers not enatiomers because the configuration of one of their chiral centers is different?

@romainrabany8278 5 лет назад

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.

Not S or R conformation, configuration is the proper word

@pythongamer3945 5 месяцев назад

Right

@trollmcclure1884 3 года назад

so there'S no easy way I can test my L-ascorbic acid without chiral stationary phase? That's what I thought

@creillyucla 3 года назад

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)
