Hi David. This simply isn't possible. We only consider one carbon at a time. So you are finding the higher priority substituent of the two on a carbon, then the higher priority of the two on the other side. We do not compare groups one on carbon with another for prioritization.
Hi zakicadde1. This is by convention. Cahn, Ingold and Prelog made that call nearly a century ago and we have stuck to it ever since. Any time a double or triple bond is analyzed in the CIP scheme, the connected atom always counts as two or three, respectively. Thanks for the question!
not sure I understand the question. There are three examples on that slide. The top two pairs are identical. The bottom pair is a set of stereoisomers.

As someone who is currently studying in France, this is an absolute life-saver for my exams next week. Thank you!
I am so glad that you found the video useful. Please subscribe to the channel, share with your classmates and come back for more videos!
thankyou so much i thought this was way harder than it actually is
Thanks, Hasan. Don't forget to subscribe, tell your friends and keep coming back! New videos are going up all the time!
Thank you so much. Yours is the most systematic and the clearest explanation I've seen.
I'm german and I have learned so much more than from all the videos that exist in german. Thanks for that^^
+Tess Partschev I'm so glad it helped!
Cannot be more clear; this is much better than Khan academy.
Thank you very much... This Video helped a lot... Using animation helps the student to understand better... Thanks a lot again
Hi Milt. I'm glad you found the video useful! You know the drill... please subscribe, like and pass the channel on!

What if your 2 higher priority groups were both on the left side (or right) of the double bond? Would it still be Z, the same?

Good video, at 7:46 why would two carbons count from the double bond.

Very helpful, I didn't understand the concept before. Thank you for your effort :)

very coherent explanation
You made the E-Z easy :)
ohhh dude this was just what i needed.thx
Great tutorial by the way the systematic name for the compound in 6:56 is E-4ethyl,3,5dimethyl, hex-3-ene is it?
+Dr. Fhood That looks right to me! Lowest number to the functional group and lowest set for substituents!

ok thanks
:)
YOU SAVE MY LIFE THANK YOUUUUUU
At 0:54, aren't the bottom two molecules supposed to be enantiomers? (you say they are the same)
not sure I understand the question. There are three examples on that slide. The top two pairs are identical. The bottom pair is a set of stereoisomers.
Excellent 👌
this was amazing. thanks alot!!!
This is great!
thank you soooo much finally i got it! i wish if my lecturer was like you lol

Thanks 🙏
Perfect!
thankss! :) ur a life saver
Thank u soo much 🙌😃
Thaaaaank UUUUU!!
Yoooooou aaaaaare welcoooooooome!!! :-)
haha : )

yw!
In India we call it cis and trans insomers
Good
Thanx
Hello TCS students!
