Naming Epoxides and Oxiranes using IUPAC Nomenclature

[@lirabilgera5016]

Thank you so much Miss Leah! Your videos have helped me survive my Organic Chem exams! You do better than my teachers. xx

[@Leah4sci]

You're very welcome, so happy I could help!

[@gabriellaquain3515]

I really enjoy your explanation. Great Leah. You teach good.

[@Leah4sci]

Thank you!

[@forlornhauntedghost]

You make naming so easy! and now I find it very easy! Thank you!

[@Leah4sci]

So glad to hear this. You're welcome!

[@yushiliang5694]

I LOVE you Leah, you made me understand finally organic chemistry

[@Leah4sci]

YAY! So happy I could help!

[@meriemhouche1840]

THANK YOU FOR THE EFFORTS,ALSO YOUR E_ BOOK IS SO HAPLFUL, GOD PROTECT YOU DEAR

[@Leah4sci]

You're very welcome and thank you!

4:27 will it be 1-chloro-2,3-epoxy-7-methylnonane or 2,3-epoxy-1-chloro-7-methylnonane

[@Leah4sci]

IUPAC nomenclature requires us to list any substituents in alphabetical order. That is why you see me place the '1-chloro' in front of '2,3-epoxy'. 'Chloro' comes first alphabetically.

[@dharshinia9378]

Thanks a lot..it was an amazing explanation... How do we name cyclohexene oxide(a.k.a epoxy cyclohexane) in oxirane method?

[@Leah4sci]

Since the longest continuous carbon chain is the ring itself (and not the oxirane), you should not see this compound named as an oxirane. You might see it as 1,2-epoxycyclohexane where the epoxy group is the substituent.

[@dharshinia9378]

@@Leah4sci Oh...thanks...also is there any special set of rules to name heterocyclic amines or how exactly do i name them?(eg: imidazole, pyridine, piperidine)

[@Leah4sci]

I'm sorry, but I don't offer tutoring over social media . For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/

[@spgplaymusic]

Does an halogen have a high priority to the epoxy group?

[@Leah4sci]

Neither takes priority. Both groups are always named as prefixes along the main parent chain. When numbering, you'll want to make sure you have the lowest total number of locants possible.

I've done just 25k no view mam...the video is very helpful👍

[@Leah4sci]

Glad to help! :)

[@akshayalakshmi9083]

Common name for 2,3- epoxy 2- methyl butane

[@Leah4sci]

There is not a common name for that compound. Only the most simple epoxides can be named using the common name ‘oxirane’.
