👉 The word '1715' is a bit of a misnomer, isn't it? It should be spelled out as '1,1 Diiodo N,N di(propan 2 yl)boranamine'. However, if you want to make an interesting point about the number's significance in chemistry, let's say it was used by a chemical physicist who calculated it to be equal to '675837 64 6' - that is, there are six atoms of phosphorus and two oxygen atoms in one molecule.
Now, if you ask someone how many atoms of phosphorous they have in one molecule, they might say "6", even though the number doesn't actually correspond to any chemical element. But who cares? The point here is to use a word that people commonly use - like '1715' - and make a statement about its significance or value.
