The n+1 rule on the ¹H NMR spectroscopy predicts A) that a multiplet containing n lines will have n + 1 equivalent protons on the adjacent atom B) that a hydrogen with n + 1 equivalent neighbors will have its resonance split into n peaks C) that n hydrogen atoms in a compound will have n+1 different chemical shifts D) that the coupling between n hydrogen atoms can only occur through n+1 bonds E) that a hydrogen atom with n equivalent neighbors will appear as peak split into n + 1 lines
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 protons giving rise to each doublet. 1 2 H3C H3C- оооооооо 238 H 8 HH HH 3 HH CH3 5 7 Identify the two groups of protons that give rise to the doublets in the spectrum. CH3 8
