Good challenge.
But may I make a suggestion: there is now a Chemistry forum in chainBB and would be good to include any chemistry challenges within it - https://beta.chainbb.com/forum/chemistry - but in order to appear there each post must have #chemistry tag or you can make a request to have, for example, #chemistrychallenge as a tag for the forum. Just an idea.
