8.0 Naming Alkenes IUPAC | Organic Chemistry
Chad breaks down how to name alkenes (IUPAC) in this lesson. He begins by naming a few examples showing how we number the longest continuous carbon chain the alkene is a part of and then use the -ene suffix at the end of the name of the parent chain. Chad then shows how to predict when an alkene will be capable of cis/trans isomerism and explains the E/Z system of nomenclature, i.e. how to use E vs Z to name such alkenes following the Cahn-Ingold-Prelog rules for assigning priority. Finally, he concludes the lesson by showing how to name polyalkenes.

Thank you - I'll take it!
Do you use E and Z or trans and Cis when naming a cycloalkene?
Keep up with your good work

Hi! Why is Carbon 9 not the same priority as the methyl group attached to Carbon 7 as both carbons are attached to 3 Hydrogens?

Hey Nicole, for this last example we care looking at the groups attached to C7 and C8 to determine E/Z. Carbon 7 has CH3 versus CH2 so the CH3 takes priority. C8 has CH3 versus H so the methyl takes priority, so in that sense the methyl group has priority in both cases. Let me know if you're still having trouble with this
God I love you and your videos ! Thanks so much for this !

at 4:21 mn For the second molecule I wrote 5-Ethyl-2methyl-4-heptene Is it wrong , why . Thank you !

Hey Asma, i know this is late but the reason why you have it wrong is because you didn’t count the carbons the proper way. When naming alkenes, ALWAYS put the double bonds in priority. So you want them to have the lowest carbon locator number. You started counting from the tail end, which gives the double bond carbon locator numbers C4-C5; however, that is not the lowest possible number for the double bond. If you start on the opposite side, the double bond then has locator numbers C3-C4, which is what you want. Always remember that you double bonds and functional groups needs to have the lowest possible carbon locator number.
thank you king

17:10 why the carbon 6 is C H H not C C H since C6 is bonded to C5 that is double bonded
@Lking123

Because we only account for what is directly bonded to it. If you say "CCH", then we are saying Carbon 6 is DIRECTLY bonded to another carbon, another carbon and a Hydrogen. But that is not the case, we have 2 Hydrogens that are not drawn on that carbon.
i got confused at the cis and trans part
I'm gonna be a short bald guy too someday Chad! You make it cool!

Hi Chad, don't you want to offer one or more (e.g. only for members viewable, except some for trial / advertising) playlist of advanced topics explained in the way you explain all your previous topics. Sorry if my English sounds strange; I come from Germany... Or one big playlist with different videos of the different advanced chemistry topics or so. Some proposals for advanced topics: quantum mechanics chemical reaction engineering advanced analytical chemistry theoretical chemistry group theory macromolecular chemistry name reactions advanced inorganic chemistry of elements and their compounds biochemistry microbiology organometallics semiconductor chemistry environmental chemistry industrial chemistry statistics in chemistry supramolecular chemistry medicinal chemistry It would be nice if you would start with the quantum mechanics playlist or advanced analytical chemistry 😉🙃 I would pay for advanced topics and there are nearly no good video tutorials in English or German. I guess that there would be many interested people in it worldwide.
