So with saying "chlorocyclohexane" its understood that chloro is in the #1 carbon spot. For the second example can we not say "2-methyl chlorocyclohexane" since the chloro would have to be at the #1 spot? And so on "4-bromo-2-methyl chlorocyclohexane"? Thanks!!
@wowmanjaro3 жыл бұрын
I typed "2-methyl-chlorocyclohexane" into some IUPAC programs and it successfully brought up the same structure.
@ChadsPrep3 жыл бұрын
Hey Joshua! I saw 1 professor accept such a name over a decade ago so I decided to do a little digging before answering. Unfortunately, my digging wasn't very fruitful. I'll start by saying that many organic compounds go by multiple names. Some are historical and some are the IUPAC systematic names. And sometimes IUPAC adopts common historical names as being proper!! And sometimes there are even multiple acceptable IUPAC systematic names (substituted benzenes come to mind). But even when this is the case there is a "preferred IUPAC name" or PIN. 2-methyl-1-chlorocyclohexane is the PIN in this case and I had trouble finding a specific IUPAC rule for a disubstituted cycloalkane that would even identify if leaving out the 1 is acceptable. So not helpful here, sorry. The exception to this that you'll learn later is if 1 of the two substituents is named as part of the parent chain then it will be at position 1 by default and the #1 is omitted from the name. 2-methylcyclohexanol for instance. Since the alcohol is named as part of the parent chain it has the priority and on a cyclic structure would be at position #1 by default and so it is omitted from the name. Hope this helps at least a little! Happy Studying!
@upleo-bj5dl Жыл бұрын
Hi, could you help me explain how some subsitutants are called propan-2-yl or butan-2-yl?
@ChadsPrep Жыл бұрын
These are alternative ways to name complex substituents...and I haven't seen them used much. Propan-2-yl is the same thing as an isopropyl group (common name) or 1-methylethyl group (systematic name). The '2' in propan-2-yl indicates that this substituent is 3 carbon substituent but is attached to the rest of the molecule via the 2nd carbon. You'll see such names used more commonly with certain functional groups like esters for example. So you might have 1-methylethyl butanoate a.k.a. isopropyl butanoate but which could also be called propan-2-yl butanoate. Similarly, butan-2-yl is the same thing as sec-butyl (common name) or 1-methylpropyl. It is a 4-carbon substituent that is attached to the rest of the molecule via the 2nd carbon. Hope this helps!

@@ChadsPrep Ah, that clears up everything. My teacher for the course (SCH4U - Ontario Grade 12 Chemistry) has mandated us to use the more IUPAC accurate name than the before IUPAC name. I've been stuck at this for a week but I couldn't stop thinking about this! Thank you - you are an amazing explainer
@mup15373 жыл бұрын
Why do we add the 1-chloro to 1-chloro-2methylcyclohexane? Why isn’t it just chloro like the example before?
@ChadsPrep3 жыл бұрын
With only 1 substituent it would have to be at position 1. But with multiple substituents it gets confusing. But I did see one professor on one occasion over a decade ago allowing students to do exactly as you suggest. But I haven't seen it again. I actually invested some time earlier this year to answer this exact question. I looked up the IUPAC rules themselves (instead of a textbook's version of them) and couldn't find it addressed specifically, so I'm going to keep teaching it as presented in all the major textbooks with which I'm familiar. Happy studying!🙂

@ChadsPrep6 ай бұрын
Hey Susan! If you look up those 2 compounds they are actually different. 3-isopropylheptane has an isopropyl group at carbon 3 rather than an ethyl group and is missing the methyl group at C2. Hope that helps!
