(b)

Interpretation Introduction

Interpretation: The various resonances to the hydrogen nuclei need to be assigned in the 1H NMR spectrum.

Concept Introduction : Nuclear magnetic resonance (NMR) is a spectroscopy technique that works on the basis that the nucleus of the atom absorbs electromagnetic radiation in the radio frequency region.

1H NMR or proton nuclear magnetic resonance is a tool for elucidating the number of protons or hydrogen in the compound.

(c)

Interpretation Introduction

Interpretation: Various resonances to carbon nuclei responsible for the 13C NMR data needs to be determined.

Concept Introduction : Carbon-13 NMR has several advantages over proton NMR in terms of its power to elucidate organic and biochemical structures. First Carbon-13 NMR provides information about the backbone of molecules rather than about the periphery. In addition, the chemical shift range for 13C most organic compounds is about 200 ppm compared with 10 to 15 ppm for the proton.
