This is so E-Z now

[@pamelag3879]

Agreed!!

Ze Zame Zide... Never gonna forget this, Thanks

[@MyTD2010]

my reaction to first part of explanation: "OOH" my reaction to second part of explanation "OHH" :)

[@TeamPill]

The title includes alkynes in it. I understand the overall topic is both alkenes and alkynes, but this is misleading, as you don't mention alkynes once in this video.

this is so helpful, i wish I had found this sooner

My professor's EZ system was not for a man of earth, but here, I got my EZ system now

[@BhavikaVarshneypakhi]

This has been brilliantly explained. Thank you so much!

[@ibchemvids]

Thanks for helping me out buddy - I got a bit confused, unfortunately it was in the middle of orgo class :)

[@LinhTruong-jk8zq]

awesome, this's so helpful, I can barely understand anything till I found your video explanation

[@mohamedhommeida2854]

Zank you Zo much zir, Zith waz very helpful!

[@paulinahambata3271]

😂😂zee what you did there

[@miaab7143]

Thank you so much, this was so helpful💚

[@blessingsmanyawi7468]

Finally the explanation is more clearer ...thanx

[@bol3iz]

5:30 why did you add an extra o on the top right side?? C is only connected to one O, not two.

[@rwayle]

It's part of the CIP (Cahn Ingold Prelog) rules which is what you use to determine priorities in E/Z. If there is a double bond you count that as two single bonds to that atom.

[@opomina5591]

Awesome course. Thanks a lot

[@pablovillanueva8006]

thanks for the vídeo, what i didn't understand for a long I've already done in this videos 😁😁💪

[@anitachen-fq3eo]

It's very helpful. Thank you so much! from Taiwan~~

[@TheUser704]

fantastic!

[@sitizuhairahzainuddin456]

I'm a pharmacy first year student and I found this video. It's very useful. Thank you very much!

[@Isomei]

Siti Zuhairah wow! Good luck i hope to be like you 💗

[@KamalKumar-ik2op]

Siti Zuhairah who cares if you're pharmacy student or not

[@j12825]

don't you need to know orgo to take pcat? how did you make it to pharm school without knowing these?

[@cornationboot8690]

@@KamalKumar-ik2op well i care

[@xxanimefanxx11]

Does anyone know when the E-Z configurations are not applicable. I'm studying for my first o chem exam and one of the questions on the review exam is determine which descriptive phase 1-6 is applicable . 4 is E configuration, 5 is Z configuration, and out of all 5 parts, 4-5 was written down on only 3 of them. SO when do you when to look for e-z configurations, if that makes sense?

[@hinaziqbal8116]

These videos are best. Helped me a lot.

[@paulinahambata3271]

Finally got this into my head😁 . Thanks#

[@MsAbby.3]

My lecturer could never😑 Thanks 🙏🏾

[@zuikisnostalgia]

I guess I'm the only one who's disappointed at the lack of complexity of the molecules. How about an example where you have a molecule that presents more than a double bond? And how would you draw it if they asked for the skeletal structure?

[@jonathanleitch6176]

zuikisnostalgia if you could be more specific I may be able to help. When you say "more than a double bond" what exactly are you referring to?

[@jonathanleitch6176]

It's also important to note that a molecule with all sigma bonds will have conformational stereoisomerism which doesn't require E,Z nomenclature since rotation around the bond is possible.

[@bulelwancamani2920]

This is so helpful . All your videos are 😭🙏

[@ysrayudu6963]

Thanks for the last example which I want😁😃

[@sairaj3265]

MASTER PIECE!😎

THANKS 🌼

Thank you so much!!!!!

[@imanhamdullah6059]

Amazing explanation!!!!

[@edgarortiz1640]

So organic compounds with double bonds aways need e z names?

[@ahadeid768]

keep going! thanks

[@kaili3477]

If the molecule is cis or trans around the double bond, do we still use the E-Z system? or do we just name it cis/trans. If the molecule with a double bond has 2 of the same group attached to the double bond (right side) from both ends of the symmetry line, but 2 opposite ones (left side of molecule). Can we still use E-Z? Do we name it E or Z? please help

[@dhiaawad6710]

so helpful

[@chemistrywithdryousafzai487]

learning the configuration E-Z now

[@Austrogirllive]

Thx for saving me

[@fauzanakhter6690]

Why did the instructor pretend that the carbon was bonded to two oxygens when in actuality it was only bonded to one? Is that how you are supposed to assign priority with other similar molecules?

[@boredpotato2176]

So damn helpful

[@witty_me]

great

[@fadheelahfaleel1487]

So whats its final name?

[@skeche]

so no more cis-trans?

[@swapnaharish9651]

so op

[@JS-vo6go]

you talk too fast, its hard to keep up. But otherwise a good video

[@breadblock]

i fucking love u
