Oh I'm I getting too geeky on you? Sorry, blame it on the movie Iron Man. It has me remembering my Biochemistry days. That is a Benzine ring and I'm a bit rusty so I think I could have added more Hydrogen Purputs to the outside of each Carbon. oops, too geeky again?
C6H6-COOH or something like that ... okay I'm stopping ... for now
