Question

The NMR spectra for compound 1 were acquired in a 7.5 mg / 0.6 mL solution of
CDCl3 The 13C peaks are also listed
below. Name compound 1 and Provide a full analysis of the NMR spectra for compound 1. with a table showing peak shift ( carbon) and assigment 

13C NMR (101 MHz, CDCl3) δ 160.79, 154.09, 143.43, 131.85, 127.87, 124.44, 118.86,
116.94, 116.74.
Note: There are two carbon peaks in the 13C spectrum that are so close together that they are not differentiable at the resolution in this experiment. 
you should be able to assign these peaks to one of two carbon atoms in 1.
