Concept explainers

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.

I sent you this question before and you answered it only till C Please give me the answers for the rest of D and E.
Chemical shift is related to electron density of the atom. Atoms with a greater electron density are "shielded" from the magnetic field and therefore have a lower chemical shift. Using chemical reasoning and the information about shielding above, provide an explanation for the trend in chemical shift for the CH2 carbon atoms based on the effect of neighboring atoms.
