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.
