Hint Since there are only 3 carbon peaks in the 13C spectra, there must be a plane of symmetry in the molecule. The UV spectrum suggests a benzene ring is present.
Organic Chemistry WH. Freeman and Company presented by Sapling Learning Peter Vollhardt and Neil Schore Deduce the structure of an unknown compound from the following spectroscopic and other data. Molecular formula C6H4Br2 H NMR 2 H 2 H 7.6 7.2 7.1 CH 8.0 7.5 7.0 6.5 6.0 5.5 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0.0 300 MHz IH NMR spectrum ppm (o) 13 C: 3 peaks IR: 7455 (s, broad) cm UV: Amax(E) 263(150), 270 (250), and 278 (180) nm Map
