Question

Does every chemically distinct hydrogen or group of hydrogens give a resonance in the NMR spectra?

Answer 1

YES

Explanation:

This is the idea behind using H NMR, is that every distinct proton has a different chemical shift and thus this will allow us to identify molecules.

Consider the following H NMR spectrum:

You can identify five distinct hydrogens or group of hydrogens and each has a different chemical shift or coupling (singlet, doublet, etc.).
