Nomenclature of Polycyclic Compounds: Naphthalene, Biphenyl, Anthracene, Spiro, Bicyclo

- We've done tons of IUPAC nomenclature for simple molecules, but once we start introducing multiple rings, things get trickier. This is especially the case because there are so many ways to get multiple rings. They can be fused, they can be bicyclic, aromatic or aliphatic, and every type has its own rules. Let's go through a few different types on ChemDoodle to see how this works!

AAAamazing！！I have never seen the APP !! Thank you.You opened the chemical door for me.
Thanks sir. Very useful
Very helpful!
8:48 why is 3,4-Xylyl given more priority?
Hiii sir please make video on some heterocyclic compound name which are related to drugs name in med chem like which contains atoms N,O, etc in heterocyclic ring or out of heterocyclic ring or both
thank you sooo much
my prof loves to ask them in oral exams!
Nice helpful to me
Nomenclature is coming out clearly
You beautiful BEAUTIFUL soul. Thank you!!!
Sir please explain the nomenclature of 9,10- Dimethyl-1, 2-benzanthracene
14:41 what if there are equal number of rings?
Where do u get that software for IUPAC naming?
there's a link in the description of the video, check it out it's very neat!
Is naphthalene iupac name?
Is there a german option in chemdoodle ? I would really like to get it but it's kind of a pain to translate everything :D
Hmm good question! I'll look into it.
Professor Dave Explains thank you :)
IUPAC = International Union of pure and Applied chemistry
5:08 Obvious question: You say we always want the lowest numbering. Why then exactly is it not 1,3,5,6 rather than 1,2,5,7? Is it lowest numbering at every new comparative step going up the chain of ascending numbers? (and not, say, lowest overall numbering given lowest first number in ascending order) Do I get a cookie? Great video btw, as always!
no it's a good question! i think that it's simply because two is lower than one, since the sum of the numbers is the same, so i think it's just comparatively lower at the first point of difference
Thanks sir i like ur all videos! ☺️☺️sir where r u living?
california!
Good work God please you
Does this playlist cover both orgo 1 and 2?
yes indeed
Sick
4:19 why is it 2 methylnaphthalene rather than 1?
because carbon 1 is necessarily a carbon adjacent to the bridgehead carbons
May i ask, what is the charge for biphenyl ?
it's neutral
Professor Dave Explains thank you Prof !!
You even look like your name would be a Dave. I dont know why or what that means, but its true.
You subconsciously think of Dave Grohl probably.
👍👍
4:48 bro it could have 1,5-dimethyl napthalene if we count it to the left side of the 1st carbon why are we not considering like that but instead taking towards right from the carbon
that's the carbon you have to start from
Same doubt
@@ProfessorDaveExplains @3:57 why you not done counting in anticlockwise manner starting from the 1st C as mentioned but going acw instead of cw will be correct as per lowest sum rule..!
.... and nobody in lab uses the iupac names😅😂
Tupac
