I was wondering the other day, in here, what organic compound would have the greatest number of elements with one-letter symbols, each appearing only once, and I reckon this might be it.
As I have made it a potassium salt we would want the potassium to replace a hydrogen in an acid, and as we have one sulfur and one oxygen, a carbothioic S-acid would be an easy option. So this would be a potassium carbothioate.
On the other side of the carbon we would have the two pnictogens in series. We can mix and match the halogens and hydrogen in various ways so we would six possible options.
One would be:
(PHI)(NF)COSK.
LOL
Let me see if I can understand this. Would the COSK be K-S-C=O or K-O-C=S ? The former I assume. The N-F makes perfect sense. Phosphane is PH3 so you’re replacing one H with an I. So that all looks OK to me.
No B, V, Y or U.
Uranium tetrafluoride is a common chemical, but we’re already running out of halides with H,F,I and K already used. Uranium halides can have a valency as low as 3, or as an oxide even 2 with UO. Yttrium tends to be trivalent. Vanadium tends to react like phosphorus, sitting below it in the periodic table, but can have valency 4 (eg. VF4) or 5 (eg. VOF3). Boron tends to have valency 3.
So, using trivalency of B, V, Y or U, It may be possible to add up to two more of these elements to your chemical if you can add another double bond, such as C=N, or make a ring. It works as follows. Adding a double bond or a ring uses up two single bonds. This frees up two halides that could then be used to attach other elements. For example you could perhaps end up with (PHI)-(BF)-(YK)-N=C=O. That’s just an example, there would be other ways to arrange it. One more double bond or ring would be needed to bring in all of B, V, Y and U.
