      • Note: In the case of alcohols on these problems, the alcohol proton is NOT coupled to the H’s on adjacent C’s due to H-bonding. Therefore the O-H proton does not participate in the splitting pattern, and itself appears as a broad singlet.

      • Example: Ethanol (CH3CH2OH):
        • The O-H proton is NOT coupled to the -CH2- protons in the structure
        • The signal for the proton on the oxygen is a broad singlet.
        • The methyl and methylene group give the typical splitting pattern of an ethyl group, showing no influence of the OH proton.
