Chapter 14, Problem 62E

(a)

Interpretation Introduction

Interpretation:

The idealized NMR spectra of the given compound should be drawn.

Concept Introduction :

Nuclear Magnetic Resonance spectroscopy (NMR) is an analytical chemistry techniques used for structure determination. Many nuclei have spin and when magnetic field is applied, nuclei can be excited from a lower energy level to a higher energy level. When spin returns to its origin, energy absorbed is emitted with certain frequency. These frequencies are measured and processed to obtained an NMR spectrum.

(b)

Blurred answer

I need the answer as soon as possible
By analyzing the COSY spectrum below, determine if it is the NMR spectrum of Compound A or Compound B. Explain how you reached your conclusion.
Can you explain spectroscopy? Let's start with NMR Spectroscopy. What is the difference between a proton being enantiotopic and homotopic? What does it mean for a proton to be shielded or deshielded? How do you determine J (the coupling constant)? What does 'coupling is mutual' mean? How is that translated on the NMS Spectroscopy spectrum? Does that have to do with the polarity of the molecule? Is there an easier way to explain that? When thinking about C-13 NRM Spectroscopy, what it meant by the statement, "the carbons cannot integrate"? When looking at an NMR Spectroscopy spectrum, how do you know which peak belongs to which proton? (The intensity of the peak and the ppm of the peak)   P.S. These questions come from after watching a lecture. There is no graded assignment attached to these questions. I simply do not understand the material.
