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.
We need to invent a cocktail called a screenshot. There's already one called a snapshot (sambuca and Kahlúa), but I think it should be a completely different drink.
