I have the NMR and IR of an organic unknown. The percentage of C, H, and O, is 71.1, 5.22, and 23.68, separately. And what are its 2,4-Dinitrophenylhydrazone derivative and Semicarbazone derivatives?
is that 4,4'-Dimethoxybenzil?
Looks like dimethyl biphenyl-4,4'-dicarboxylate to me.
See attached
4,4'-dimethoxybenzil
