Thank you! :) Don't forget to subscribe.

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!

Thank you and good luck on your exam!

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 :)

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!

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!

@Leah4sci

3 жыл бұрын

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?

Thnx... Thnx a lot

@9:33 why do we start counting from the left? doesn't the double bond get priority ?

@Leah4sci

3 жыл бұрын

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.

Wow, where did you buy that molecular kit?

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.

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

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 🍯💜🤩
