The volatile organic compounds (VOCs) produced by decomposing tissue and organs were studied in an effort to identify possib human-specific markers (PLoS ONE 2015 10(9): e0137341.). Of 452 VOCs isolated, six were found to be unique to humans, so th prove to be a useful tool for forensic chemists trying to determine the source of unidentified remains. There are two doublets in expected ¹H NMR spectrum of the following human-specific VOC.

Identify the significant absorption peaks by labeling them right on the spectrumand includethe spectrum in your laboratory report. Absorption peaks corresponding to the followinggroups should be identified: C—H (SP3) C—H (SP2) C—H (aldehyde) O—H C=O C=C (aromatic)aromatic substitution pattern C—OC—X (if applicable)
A student needs to prepare a ¹H NMR sample for an organic compound soluble in chloroform (CHCI3). The student cannot use CHCI 3 as the solvent for the sample, but rather uses deuterated chloroform (CDC13) because: O CDC13 is more polar. O CDC13 will not produce a signal in the ¹H NMR spectrum, and therefore will not mask the signals of the compound. O The compound will be more soluble in CDCI 3. O CDC13 is cheaper than CHCI 3.
