    Oh by fucking gods. It’s loss. People are STILL posting loss. And here I was thinking this was a chemistry meme.

    Fixed the charge on your 3-methyl-3,4,5,5,6-pentaethyl-6-butan-2-yl decane ion, aka lossane.

    (It’s been a while since I last did chemistry, so apologies if I messed up the nomenclature a bit)

      actually we start numbering by minimising the number of highest order addition, which is the isobutyl, if it gets same number regardless, then we try to minimise the sum of numbers, so i think it should be called

      5-(isobutyl)-5,6,6,7,8-penta-ethyl-8-methyl-decane (I am assuming hydrogen’s are present, just not represented, because that usually is the case)

      I may alo be wrong here, it has been 4 years since I have been required to do nomenclature myself

        Ah, my chemistry department taught me the other way around. I distinctly remember the phrase “methyl-ethyl” being thrown around a bit. Additionaly, we were taught to be more specific about isomers, hence me using butan-2-yl instead of isobutyl.

        Then again, scientists often disagree strongly about things like this, so we could both be right. Also, there’s a good chance this is just the A-Level specification being weird. I left my old textbook at my student flat, though, so I won’t be able to check for a couple of weeks.

        I could also be downright wrong myself.

        As for the hydrogens, I had assumed they were not present, and that this lossane molecule is an ion with a charge of -50. This is borderline impossible to achieve in real life, of course.

          Now i remember we also had to specify what isobutyl (technically just 1 isobutyl exists (not counting stereoisomers), and other form would be tertbutyl). But giving highest priority and minimising sum were definitely something we were taught.

          I was free enough to look it up this time - IUPAC guidelines for organic chem - https://iupac.org/wp-content/uploads/2021/06/Organic-Brief-Guide-brochure_v1.1_June2021.pdf (or more generally https://iupac.org/what-we-do/nomenclature/brief-guides/)

          Section 7 ( c ) Lowest locant(s) for principal characteristic group(s)

          Although I also remember just as we completed our unit on nomenclature, all we got was “common names”, now i was supposed to know of the top of my head what a cumene is (which I think is isopropyl benzene (not going to check this one)). Same thing happened with polymers, we were taught IUPAC, and then again, “industrial names”

      As someone who paid enough attention in highschool chemistry to get a B, and occasionally watches Nile(red/blue) and E&I videos… I know some of these words/symbols!

        Fuel? Hydrocarbons like that are quite combustible. It could also be incorporated into a lipid or something.

    Assuming this has a 47 hydrogens stuck on to make it stable, I’d call it:

    3-methyl-3,4,5,5,6-pentaethyl-6-buta-2-yl decane

      dodecane has a 12 carbon chain. The longest chain here is 10 carbons, which would be decane.

      I am a total chem nitwit, would you like to explain me how you come to this ?

        It basically comes down to finding the longest chain of carbons, then you number each of the carbons on that chain and list off things that are attached to each of them. For example, 1 carbon = methyl, 2 carbons = ethyl, etc.

    Can someone explain this to me? I don’t get it, but I want to.
