Great videos Dave, as always. Love the IUPAC concept when all the professional heads got together and essentially said: "We'll name everything with a distinct order and use the alphabet to our advantage for simplicity, except when it doesn't suit us, in which case we'll just do this with iso."

@adhiyanthaprabhujeyashanka2091 2 года назад

Do we list halogen groups firstly in the name ? Because in the last nomenclature example professor dave just mentioned 6-iodo first despite the fact that hydroxyl group appears first alphabetically

@gimme_a_good_name_bruh 2 года назад

The hydroxyl group must be the most important ie the functional group. The halogens are substituents

@hebashahid8952 3 месяца назад

it's because of the suffix OL Alphabetically OL would come afterwards

Hi. In the last example, why was iodine named first instead of the hydroxyl group? Sorry little confused with the alphabeticity

@ProfessorDaveExplains 5 лет назад

so a hydroxyl modifies the suffix of the molecule, "ane" becomes "ol", so we name it at the end. things like alkyl and halogen come first but more significant functional groups are part of the parent name

@alexiamiladinov8393 6 лет назад

Hi Dave, I am wondering if there is a specific language alphabet that you use when naming the molecules. For example if we have the 1,3-dibromo-2-chloro-4-ethylpropane molecule and if I'm supposed to write it in swedish instead chloro would be kloro and then I'd have to write 1,3-dibromo-4-etyl-2-kloropropan, would this be correct or do I have to think of the alphabetic order of a specific language, for instancde English?

@ProfessorDaveExplains 6 лет назад

oh interesting! well i think IUPAC set all the rules for the english language only, so i don't really know how it would work in other languages. i would just learn everything in english though, that's the official language of chemistry!

@saurabhsibal00 6 лет назад

Hi, when naming Haloalkanes, I have heard of conflicting rules in terms of which element gets the lower number (if the numbers end up being same from left to right or right to left). In the video, it is mentioned that the “one occurring sooner alphabetically” gets the lower number. But, other places I have heard say that the most electronegative will be assigned to be the lower number. Which way is correct according to IUPAC (alphabetical or electronegativity)?

@ProfessorDaveExplains 6 лет назад

interesting! i had always heard alphabetical, but it is a situation that comes up so rarely that i never even really checked. i would be curious to read something that mentions electronegativity. it seems unlikely, because then the person may have to look up an electronegativity table, whereas alphabeticity is obvious, and the rules are arbitrary after all.

@saracululejevic7950 7 лет назад

So Dave do all halogens in a compound naming come before alkane side groups or is it just alphabetical? In the first example u had methyl last just because its alphabeticly last or not? Also in case the methyl was the nearest to the first carbon in the chain would the numerical order go after the methyl group? Thank you!

@ProfessorDaveExplains 7 лет назад

alkyl and halogen have equal priority, so all of them will just be placed in alphabetical order!

@ProfessorDaveExplains 3 года назад

You can place the number in either location. Most chemists place it before the parent molecule. And if you place it within the word, you need hyphens on either side.

@leowo9 9 лет назад

In the last example, wouldn't iodo come after hexanol as 'h' is sooner alphabetically than 'i'?? So the final name would read this way: 2-hexanol-6-iodo...?

@ProfessorDaveExplains 9 лет назад

Vasu Singh the parent name of the molecule is hexanol, so that will go last, after we list all the substituents.
