In this clip, the Cahn-Ingold-Prelog Convention is introduced, to allow for assignment of absolute configuration of stereocenters. I dunno why it took three dudes to make the convention, but it's pretty sweet if you think about it.

I just graduated with my undergrad and I had never thought of the different spatial orientation view... The way you explain things makes so much sense! Thank you!

@clark0660 8 лет назад

The amount of views is waay lower than it should be, you are great at explaining concepts. Also, nice hair!

@katraam 3 года назад

Not exaggerating but I swear down, your videos are sooooo much easier to follow and understand. You just seem to make all the pieces fit together! Thank you a million times over for your videos, they are saving my sanity! 😂

@Mrjmaxted0291 5 лет назад

Holy crap this contents amazing. Please keep making these, easily the clearest and most concise chemistry tutorials online.

@sunehrikiran5638 6 лет назад

I've seen many of your videos they are all to the point .Easy to understand . You explain very well that it leaves me with no confusion .

@liyamariyamsalman5276 3 года назад

I had been spending hours figuring out R and S and the E and Z config!!! But prof Dave.. You have saved my day.. Your videos are super cool and way way easier to process mentally than the hours of lectures i have heard.. Thank you sir❤

@to181 5 лет назад

I was having issues with spacial imagination until I saw you look at the hydrogen and imagined it in the back and then you could see all the 1,2,3 priorities in the plane. Thanks so much!!

@michaelleonardlubiano3912 6 лет назад

You have explained the Cahn-Ingold-Prelog convention well, my dear Prof Dave! Thank you so much!

@langelihlekhumalo2860 4 года назад

Wow, this was super helpful!! The way you explained it and made it so simple makes me feel dumb for not getting it in the first place😂

@khadzdama6700 4 года назад

Thank you honestly. I just watched your isomers series and it helped me more to understand what a university proffessor couldn't explain correctly.

@riceyeti5224 4 года назад

Literally this is the greatest channel to ever exist. It is saving my o chem grade because I am ACTUALLY LEARNING SOMETHING!

@thecoreybrown 4 года назад

Thanks Dave! You really have helped me over the years! You are a TON better than Crash Course!

Hope Crash Course doesn’t see this comment🫣

@13Drumsticks 7 месяцев назад

Once again beautifully explained and a perfect refresher to come back after a long time out of OC. Thanks so much!

@joyceampong2756 5 лет назад

@DatDack 5 лет назад

the fact that my profs try to make us waste our time building every molecule to assign R and S is absurd - thanks so much for this new technique, it's so much more efficient!

@khanrauf4024 3 года назад

man youre great watching you for like 3 years

@motivational_Insights Год назад

thank you so much. I have looked everywhere until i got you. this explains my predicament. I knew the wedge or dashed hydrogen but when in the plain the textbook I use said nothing about it. Thank you so much

@poodles4058 7 лет назад

Professor Dave Explains but if they do not give where the wedge bond and dash bond is how would I know whether the hydrogen is in the front or back of the compound

@ProfessorDaveExplains 7 лет назад

prathyush srinivasan good question, you can't! some kind of three-dimensional notation must be used to assess stereochemistry.

@poodles4058 7 лет назад

Professor Dave Explains oh okay
