Isn't that simply because the electronegativities of the pseudoatoms B2+ and B12- are not the same though, at some level?

In short, I probably wouldn't, at least not in isolation. I may have an inkling of how my unknown was made, or other spectral data. Also, in 1H NMR these are usually integrated, which may also give a clue.

I don't disbelieve you as such, but consider https://en.wikipedia.org/w/index.php?title=Special:CiteThisPage&page=P-Toluic_acid&id=738054995 - is this incorrectly stating the preferred IUPAC name then?

Peaks, or environments? Each of the protons is different in malic acid, so feasibly you could see 6 different environments.

Just be careful with your language. 0.33333333333333333333... (to infinity) is also an infinite decimal, but can be written exactly as 1/3.

The "order" of something is an approximation. If given correct data you calculated the time it takes Usain Bolt to run 100m to be 0.1 seconds, 1 second, 10 seconds, 100 seconds, or 1000 seconds which is most likely to be correct? But if you're taking both figures as diameter, where has the 0.5...

I would think so, but just rereading the question, are you assuming that the figures given are radius, or diameter for both figures (minor point)

No error. It's approximately 1 metre, as opposed to 1 kilometre, or 1 millimetre.

Not necessarily a fallacy. You are asked for the "order" of the size, not the "exact" size. What this means that as long as you have approximately the right figure you're OK and is a useful check. You may have made an error mathematically or otherwise and calculated this as a kilometre, or a...

But then g is not equal to 9.8 ms^-2 either, unless this has been specifically mentioned earlier, even with the restraint of "at sea level"

And 4 sides and 1 diagonal is not sufficient either. Consider a shape with sides 1, 1, 0.8, 0.8 in that order. Now the 0.8 v can be inside, or outside (convex or concave) with the area different.

How about three quarters of a minute, over a whole day? (actually it's 43.2 s, not 45 s; but maybe that's close enough?)

Off the top of your head, what do think may happen? Did you observe any evidence for a reaction?

Can you see what functionality there is in your starting materials that will undergo the reaction?
