Step 1
According to the given organic compound formula, the double bond equivalent (DBE) = 10 - (8/2) + 1 = 11 - 4 = 7
So, this means that the compound should have present unsaturation. As all the 1H NMR peaks come at the 7 to 8 ppm region, the compound should have aromatic benzene ring. Now There are number of unsaturation is 7 and all the peaks are in the deshielded region, so the compound should contain 2 fused benzene ring.
