All protons in the same magnetic environment are referred to as an equivalent set of protons. Each equivalent set produces a signal in the 1H NMR spectrum. Label each equivalent set of protons (a, b, etc.) in the compounds below. Circle the set that would appear most downfield in the 1H NMR of each compound. CH3 CH-C-H CH3 B.

H NMR Spectrum:
For each signal:
1.) Identify its environment
2.) Identify its spin-spin coupling (identify how many protons
are 3 bonds away, causing the coupling)
3.) Identify its integration value
