What are your thoughts? What functionality is there?O[C@H](C1=CC=CC=C1)[C@H](C2=CC=CC=C2)O.

The structure shown is: 1,2-diphenyl-1,2-ethanediol. I'm pretty sure that my stereochemistry is correct (it's the meso isomer)... but how do I incorporate the S and R labels into the name of the compound to give its full name?

Wouldn't the name be (1R,2S)-Diphenyl-1,2-ethanediol? Or am I wrong?

Is meso-1,2-Diphenyl-1,2-ethanediol the correct name for this compound?

Almost, where are the phenyl groups?

Is meso-1,2-Diphenyl-1,2-ethanediol the correct name for this compound?


I imagine this would probably be good enough, colloquially, but not by IUPAC
