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?
@Leah4sci3 жыл бұрын
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!

How is cis and trans different from E and Z configuration? I mean with the examples above, why not using E and Z?
@Leah4sci3 күн бұрын
Some pi bonds can absolutely be categorized using cis trans AND E/Z notation. That being said, cis/trans specifically refers to an alkene with carbon substituents for example cis vs trans 2-butene. E/Z refers to a pi bond with anything on the pi including carbon, halogen, or anything else. Additionally for Cis/trans you tend to have just one carbon attached to each sp2 carbon, while with E/Z you can have multiple groups that require ranking using the Cahn-Ingold-Prelog system

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!
@Leah4sci3 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?

@9:33 why do we start counting from the left? doesn't the double bond get priority ?
@Leah4sci4 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.

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
