Can Wolfram Alpha Beat OPSIN?

The chemical blogosphere has started to have fun with Wolfram Alpha ( and links from it), so here’s my contribution. Is the following picture a (bad) lookup? Is this an attempt to parse the name? After all a single character m shouldn’t matter to the greatest brain ever.


(For non-chemists it’s got the structure of dibromoMethane instead of dibromoEthane).

I think we could bet on OPSIN beating WA in a contest.

  1. Sort of an unfair competition – hopefully OPSIN (or some other name2structure program) would complain that “dibromoethane” is ambiguous – are you interested in 1,1-dibromoethane or 1,2-dibromoethane?

      I tried locants and it didn’t have answers so I tried something more generic. I don’t mind it not having answers – just more worried when they are wrong.
