Very well put together video and I actually have a question. When would you use bis or tris in nomenclature?
@daniellagarcia1552
@daniellagarcia1552 3 жыл бұрын
when ordering alphabetically you ignore the prefixes that come with a dash ( sec- , tert- , ect) and the numeric prefixes (di, tri, etc). In your example on 18:46 dimethylpropyl actually goes after diethyl

Hello Daniella! For simple substituents (like ethyl) you ignore the numeric prefix (di, tri, etc.) when determining alphabetical order. But for complex substituents (like 1,2-dimethylpropyl), you use the first letter in the name of the complex substituent even if it is part of a numerical prefix (I didn't make the rules). So diethyl, being simple, is alphabetized under the letter 'e.' But 1,2-dimethylpropyl, being complex, is alphabetized under the letter 'd.' Like I said, I didn't write the rules. Hope this helps!

Near the end of the video at 22:58, should isobutyl be placed in parentheses since it is a complex substituent, or is it not because it is a common name and not a systematic name? Thanks.

Is the carbon attached to the longest chain really always No. 1 in the substituent? Because Chemsketch software tells me that the substituent you are looking at in 16:36 is called (3-methylbutan-2-yl)
@badalrakshit9200
@badalrakshit9200 3 жыл бұрын
Sir if there is a functional group in the complex substituent, then the numering will be done from the functional group or the carbon attached to the parent chain.

For your first example at 18:50 isn't it backwards since diethyl is closer to the alphabet than dimethyl or am I missing something?
@sciencenerd7639
@sciencenerd7639 29 күн бұрын
Nah the way Chad has it is right. Remember that for the simple substituents the numerical prefix does not count for alphabetical order and that for the complex substituents the numerical prefix does count for alphabetical order.

Good sir, we use prefix such as bis tris and tetrakis if the exact same complex substituent is present in 2 or more locations. My question is do we consider bis tris etc while choosing the first alphabet to order the parts of the name of molecule.
