@@yogikaadda9664 That's awesome! This Chem Libre page also does a great job with explaining the nomenclature ( chem.libretexts.org/Bookshelves/Organic_Chemistry/Map%3A_Organic_Chemistry_(Smith)/Chapter_17%3A_Benzene_and_Aromatic_Compounds/17.03_Nomenclature_of_Benzene_Derivatives ).
I get confused when he pronounces words that ends with "-yl" and "-ol" or "-o". Are there any indications that he is saying, for example, phenyl and not phenol? or Acetyl and not aceto? or Nitro and not nitryl? :')
Thank you But u did not mentioned which has the highest priority when naming the parent chain How to know which one to choose nitrobenzene or benzoic acid ...as parent chain?
I have a question about the last example, how come the NO2 was included when counting despite the fact that it's a parent compound on it's own (i.e Nitro Benzene, as earlier stated) just like the OH and the COOH were in the two questions preceeding it? Does this mean that if an Aniline (NH2) is given in a similar question it would also be counted, making the answer to be something like 4-bromo-1-chloro-2-aniline benzene? Cos you said that once a parent compound is identified, it's automatically number 1, but you didn't do so for that last example, it was as though you took the parent compound to be just Benzene.
Thanks a lot for your amazing explanation it's helping me since I was in highschool and I'm still watching your videos, if I faced any problem in Chemistry or Maths I start looking for ur help. God bless you 🙏😇❣️
wouldn't the last example be 5-bromo-2-chloronitrobenzene , because wouldn't the NO2 with benzene ring make it the parent name and therefore start at NO2, not Cl?
Halogens and nitro group have the equivalent priority. So you only need to number it in a way that gives the substituents the lowest numbers. Whatever's #1 is the parent name.
Aromatic nomenclature? More like automatic know more, greater! Thanks for making all of these wonderful videos and sharing your knowledge with all of us on RU-vid!
@@mawddahll1911 are you sure? I read in a book the priority order is -COOH, -SO3H, -CHO, -CN, ......-R, -NO2, -X. So halogen is the last priority based on the book. But based on the link given above you are right.😅 I am confused now
