What information can we gather from these three spectra (IR, H
NMR, 13C NMR) to correctly identify the unknown compound? What is
the identity of my unknown? Please explain how we get there and
from what information we do so. I understand that I must initially
use the rule of 13.

Draw the structure of the compound C_9H_10O that exhibits the^13C-NMR spectrum below. Impurity peaks are omitted from the peak list. The triplet at 77 ppm is CDCl_3. Used with permission from Aldrich Chemical Co., Inc. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. Do not include lone pairs in your answer. They will not be considered in the grading.

Need help as soon as possible, my assignment is timed but I don't know how to complete this. This is all I was given in the question, nothing more was provided. --First, using the molecular formula of C7H10BrFS please draw a bond-line structure and the corresponding 1H NMR spectrum. Second, using the same molecular formula, please draw a constitutional isomer and the corresponding 13C NMR. Please be sure to have both representations properly drawn as well as the corresponding spectra.
