NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

(C) Substitution of an amino group on the
para-position of acetophenone shifts the
C=0 frequency from about 1685 to
1652 cm-1, whereas a nitro group

What can be a reasonable hypothesis from the following observed in vitro data? Compound 1 Kd = 20 nM Compound 2 K₁ = 35 mM There is an important hydrophobic interaction at the binding region. There is not much space at the binding region, so removing the aromatic ring increases affinity. O The removed aromatic ring is not part of the pharmacophore. O The removed aromatic ring was getting metabolized and subsequently easily eliminated. O Changing the methoxy group for an electron withdrawing group will result in decrease of affinity.

Your answer is incorrect. The volatile organic compounds (VOCs) produced by decomposing tissue and organs were studied in an effort to identify possible human-specific markers (PLOS ONE 2015 10(9): e0137341.). Of 452 VOCs isolated, six were found to be unique to humans, so this may prove to be a useful tool for forensic chemists trying to determine the source of unidentified remains. There are two doublets in the expected ¹H NMR spectrum of the following human-specific VOC. Identify the protons giving rise to each doublet.
