I can only reiterate what has been said in the comments. I have absolutely no explanation for those downvotes. The downvoters (on these specific posts, in this specific case!) should declare why they voted down the question. In my opinion it is a good question because:
- it shows how it is an actual problem you ran in to
- you show your thoughts and ideas on how to understand/rationalise the fact
- you provide clear pictures and point out where your confusion still lies
- it is phrased in readable English and only contains one question mark per sentence
In fact, I just read it and upvoted it. Similarly for the answer. It is not quite up to par with orthocresol’s usual answers — yet. I believe that we won’t have to wait long for a nicely drawn scheme explaining the fact better to turn up. Of course, it could still highlight that an inverting compound is not actually a meso compound and whatnot, but also that answer deserves upvotes. Hence I upvoted it.
I find it sad that at present my single upvotes are struggling against three question and two answer downvotes!
