Recently we had this challenge in our Organic Chemistry Department. I was not involved in it but I thought it might be interesting for the SE Chemistry site, so here it is.
Propose a structure for C20H18 with the longest IUPAC name. Following rules apply:
- Names must be generated with MarvinSketch: Structure>Generate Name…>Preferred IUPAC Name (https://www.chemaxon.com/products/marvin).
- No isotopic markings can be used.
- The structures must be possible (no cycles with too much unsaturations nor systems with impossible tension).
- All the characters will be counted: numbers, letters, points, colons, dashes, everything.
- Longest name wins.
Here is the example that was given:
and the name provided by MarvinSketch:
Good luck and prosperous year 2018!
Well, what is a challenge without a prize? So, I have set a bounty worth +50 reputation for the longest name. Sorry, I can not spend much more on it. Remember that you can post more than one structure. If you have proposed one and after some days you find a structure with a longer name, you can post it too.
