The IH NMR spectrum of 1-propanol displays a singlet for the Oh proton instead of a triplet. Explain why.
a. This is typical of all protons bound to oxygen.
b. 1-propanol is too small for coupling to occur
c. 1-propanol molecules rapidly exchange the OH proton, which prevents splitting
d. The signal for the OH proton is out of the normal range of the ¹H NMR spectrum meaning that it is not usually visible
e. OH does not generate a proton signal due to the highly electronegative nature of oxygen
