Omg you have no idea how much timely this was! We JUST covered cis and trans isomers and I was scouring your website and your channel trying to find something but couldn't. BLESS, there is someone watching over me! You're awesome, thank you for everything you do!
i can't say thank you enough for your channel. i'm currently studying for my second o-chem 1 exam (which is in a week) and watching your videos is a great way to review!
COVID & Online Uni has made studying/understanding chem concepts so difficult. However, your videos convey the material so beautifully. I really enjoy learning chem because of your videos! Thank you so much :)
hi, for the last example, what is the name of that molecule? i am studying with friends over zoom and we are all wondering!!! thank you so much we love your videos leah!!!!!!!!!
Sorry for the late reply! The molecule at 9:17 would be named (3Z, 6Z)-1,3,6-octatriene, using the E/Z notation. The molecule at 10:27 would be named (E)-3-methyl-3-hexene.
This video was so helpful. Thank you. But, at 9:20 wouldn't you start at the bottom since there are two double bottoms, and also since you want the lowest possible numbers?
If I were naming this molecule with an IUPAC name, you would be absolutely correct. I’m not attempting to name this structure, however. I am simply trying to identify the double bonds as either cis or trans. There was no meaning in the direction I chose to start with. Sorry for the confusion!
But... I had a doubt that here in class of halogen, even though they are halogens but they are different,I mean chlorine and bromine , so how could be we can say it's a cis... Because from my studies I understood that same group on same side we can call cis, in opposite side it's trans. ... Please correct me or giving me an explanation if I am wrong
I don't understand which example in this video you're speaking about. For more on identifying cis and trans, make sure to visit my tutorial at Leah4sci.com/CisTrans For further questions, you can also contact me through my website at Leah4sci.com/contact
Great question! Make sure to see the next video in the series, along with the full tutorial, found at Leah4sci.com/CisTrans to learn about the E/Z system of naming.
Hi! I had a question on my homework that was asking what cis and trans cyclobutene would look like, but I couldnt find it anywhere. How would those compounds look like? Would it be similar to the compounds drawn at 9:14? Thanks!
Thanks for watching and commenting! Cyclobutene does not have any substituents, and therefore, has no groups to be placed cis or trans relative to each other. The pi bond itself cannot be cis or trans either, because of the severe angle strain present in a 4-membered ring. Are you sure your question is talking about cyclobutene? Or maybe it could be something like 3,4-dimethylcyclobutene?
Great question! If I were looking to name this structure, you would be correct. We would count from the direction that gives the double bonds the total lowest numbers possible. However, in this problem, I was simply looking to identify the configurations of the double bonds.
I'm so great full for share this fucking usefull video girl , you cant imagining how it gave me a view to understanding cis and trans And also you had a clearly speaking even for me because Im not native Thanks honey 🍯💜🤩

You're very welcome!
I don't know how to thank you...you always make it so easy.
You are so welcome! I'm happy to help!
Thanks Leah! Your content is really helpful!
You're welcome!
Beautiful explanation!
Thanks! Glad you liked it!
best super best teacher u are...
best explanation
Thank you! Glad to help.
hi, for the last example, what is the name of that molecule? i am studying with friends over zoom and we are all wondering!!! thank you so much we love your videos leah!!!!!!!!!
hope to hear from you soon leah!!! :D
pls our exam is this saturday D: we love you leah!!!!

Awww thanks!
best explanation. hats off for you. I am also a chemistry teacher and author.
Glad you liked it!

very good explanation
Glad you think so!
paying 4K for my ochem class and my professor can't explain this as well as you do. thank you very much!
You're very welcome!
Thank u so much I finally understand this 😢
I'm so glad to hear it! You're welcome.
God bless you
Thank you!

Wow, where did you buy that molecular kit?
Glad you like it! I talk about it on my website (including where I got it) here: leah4sci.com/kit
Please make videos for hydride shift and methyl shift

excellent video super job
Thank you very much!
Thank You ma'am.
You're very welcome
so what’s the name for the last molecule

@9:33 why do we start counting from the left? doesn't the double bond get priority ?
Great question! If I were looking to name this structure, you would be correct. We would count from the direction that gives the double bonds the total lowest numbers possible. However, in this problem, I was simply looking to identify the configurations of the double bonds.
Nice explanation, Could you suggest where I can buy these model (boll and stick type -carbon-hydrogen)?
Yes, I have links to it and other resources to help you best use your kit here: leah4sci.com/how-to-use-your-organic-chemistry-model-kit/
Where can I buy the 'atom stick' model to play with?
I talk about the model kit and where to buy it here: Leah4sci.com/kit
Thnx... Thnx a lot

I'm so great full for share this fucking usefull video girl ,
you cant imagining how it gave me a view to understanding cis and trans
And also you had a clearly speaking even for me because Im not native
Thanks honey 🍯💜🤩
Wow, you're so welcome! Happy to help you understand!
Jesus Christ is waiting for you with His arms open wide!😄
Thanks for your kind words
Indian here: your explanation is wrong
Thanks for letting me know. What, specifically, are you referring to? And can you give a time stamp?
