nomenclature of heterocycles fused rings

[@Mimi44892]

I've spent 6 hours trying to understand this part by reading books. Came here and I can't believe how easy it is. Thank you so much.

[@priyakaushik4713]

Really sir, you made me awestruck.. For a while.. With what an ease you were explaining and it was going inside my head... I'm lucky enough to find your channel and got such a wonderful explaination. Keep coming with your wonderful session... Sir... Thank you so much Sir.

[@vikramjoshi3452]

Thank you sir! Our college teachers don’t teach us this. Keep doing such videos, it’s really helpful.

[@ghanemahmed3785]

thanks sir for this >> but i have 1 question >>in the 24:00 min in the nomenculture u started numbering the minor ring from the unsaturated N of structure >>i think we should start numbering from the saturated N >>forgive me if my English writting is not understandable or not clear

[@faryalanwar1618]

Same question plus he considered it clockwise but it's anticlockwise

[@joelgouado7759]

Probably late but you are right Ahmed! he should've started by the least saturated, and we'd have had [4,5-d], but everyone makes mistakes I guess.

Thank you so much sir I have exam tomorrow clearly understood everything. Since 3months I was tired of practicing and still didn't understood ,after watching this I got it all.tysm sir. 👌

[@vinitarao7721]

Very well explained.. thanku sir my doubts are clear now

[@LuisMendez-nw2up]

Lovely explanation Dr. Murali. I want to know how to name the first compound when the minor ring has a hydroxyl group or a carbonilic group please (for example, X aromatic position). Sometimes I have seen like that "1H-benzo[d]1,3-diazol-Y-ol" why not? "Y-hydroxy-1H-benzo[d]1,3-diazole". I hope to hear from you and your help. Thanks in advance.

[@PSRChannel]

Former name is not correct.. hydroxy shall remain a functional group on a ring. Hence the name cannot be...ol

[@aleenakhan4392]

can someone please help me that from where i start numbering the whole system for indicating saturation like "H" in fused rings....

[@MohitKumar-bv1dw]

Pouse video at 25 min, Here, if we start numbering from 2nd -N of highlighted ring, then we get locant [1,2,3,5] which lower than locant [1,3,5,6]. Will it be correct ?? Please reply... Regards: MOHIT KUMAR M.PHARM. UTU Dehradun.

AsSalam o Alaikum! 1)Sir if numbering of major ring is in Anticlockwise direction and numbering of minor ring is in clockwise direction then number will be written in brackets from minor ring but how they will be written in the form of Anticlockwise direction (major ring)or clockwise direction (minor ring) ... kindly reply must and clear this Confusion plz

[@mayankkaushik3034]

[@kaustubhdagare8705]

Is heterocyclic compounds and fused heterocyclic compounds are same or different... What is difference between them?

[@PSRChannel]

If more than one heterocyckic rings are fused to form new heterocyclic ring, that's a fused heterocyclic unit. It's a heterocyclic ring only. Purine ring possess a pyrimidine and imidazole ring in it's structure

[@abinashalagar5088]

sir . shall we put 3H instead of 1H by representing the hydrogen with 3rd nitrogen..? please clear my doubt sir..

[@hrithikchatterjee1773]

At 9.59 it is not same direction one is anticlockwose other is clock wise??

[@aniketnagwekar7730]

In 20:50 why didn't you started numbering from oxygen atom in oxazine ring, cause then the number to heteroatoms would be (1,2,4) ?? 😅

[@joelgouado7759]

The numbering should start on the atom adjacent to the junction. This is not the case for that Oxygen. Probably late but hope it helps.

Sir.. I am confused bw anticlockwise.. And clock wise.. Please clear it..

[@PSRChannel]

The direction in which clock hands move.. if you also move around the structure while numbering, its clockwise direction. If you go in opposite, its anti clockwise
