Naming Alkyl Halides

[blasianniggah]

Isn't it call 1-bromo-1chloro-2,2,2 trifluoro ethane?? because according to the alphabetical order rule???

[XDecagraphX]

Can it not be -1-trifluoro and not 1,1,1?

[HoboProber]

@XDecagraphX You have to state where the halides are - as with any functional group. Implication isn't enough unfortunately.

[BadVilbelStudios]

I love yooouuuu <3

[ewkudnd]

why didn't we start from the bromo as 1 and let the floro be 2. dat is. 1-bromo-1-chloro-2,2,2-tri fluoro ethane.

[masterkill95]

How about the Hydrogen, isn't that a methyl-group ?

[98JMA]

@masterkill95

No, a lone hydrogen is just a hydrogen and in these cases it doesn't really matter. A methyl group has one carbon and 3 hydrogens.

[Wexo0o]

@masterkill95 no its methyl when its CH3 only :D

[kourosh89]

Why is the carbon with 3 fluorines labelled as #1? What one carbon had 3 fluorines, and the other had 3 chlorines? How would you decide how the carbons are numbered in that case?

[noisemakerification]

@kourosh89 the number of flourines is represented in the "tri", the position of the flourines is represented by the "1"s.

you can choose how you want your carbons numbered, but you just have to stay consistent

how to download this Video ? ? ?

[armalik17]

@cleolander25 use youtube downloader. google it

[cleolander25]

@armalik17 thanks ..

[shad0wfaux]

You are my new hero.

[trendline2u2]

awesome!!!

[Nellysan916]

Yeah he missed the methyl group didn't he?

[pepteamsergi09]

what happened to the Hydrogen?????

[shanosan]

Although... I think it should be 1-bromo, 1-chloro, 2,2,2-tri-fluoro-ethane... to respect alphabetical order and match lowest locator number to ABC.

[wendy033081]

@shanosan the C where the 3 F's are attached should really be C no. 1 because it has more halide substituents attached to it (3F's) compared to the other C which only has 2 (1 Cl and 1 Br)

[dariajelonek]

@wendy033081 what if the 2nd C that has 2 substituents had 3.... 2 bromos and 1 chloro... wold that become your 1 then? does the alphabet kick in there?

[shanosan]

Because you always have to put the locators. It could also be 1,1,2 trifluoro if one of the fluorines was on the 2nd carbon...

[rinwhr]

5:33

Why is it 1,1,1-trifluoro? Why couldn't you have done 1-trifluoro?

[WeezyInfected]

@rinwhr they all need locaters. You can't assume that someone will know all three are on carbon 1. IUPAC.

[rockediny]

do you use a mouse to write?

[MsWaii]

@rockediny pretty sure he has a tablet.

[flndrs137]

i get this, thank you

[ose90]

finally :D

[homousios]

thanks Sal. You made this comprehensible

[PoleReseal]

sweet Sal! I was just about to request organic chemistry videos, and here they are! Are you going to do some biochemistry (proteins, carbohydrates, fats etc) videos? And also some biology videos on the digestive system would be really appreaciated. Thanks for the great work your constantly putting out there for all to use.

[dzhitler]

yes that's it,

thank's for sharing

[zappdanko]

seriously, thank you very much!

[921144666]

This is great! thanks! :-)

[zackboomer]

great organic chem vids. i never really tried that hard in high school orgo or 1st year organic chem but im going to use these vids next year in organic chemistry.

[Underfaith]

Love your Videos I watch them all and they have greatly helped me grasp harder concepts. Keep it up!

[wookieman3]

how come you have to note that the name is 1,1,1 -trifluoro if all the fluorines branch from the same 1 carbon?

[Veradrix90]

Love it, thanks khan!!!
