An alcohol with molecular formula C4H10O gives a 1H NMR spectrum with two peaks. The relative areas are shown. The peak at delta 1.2 is a singlet; the peak at delta 2.0 disappears when D2O is added.
The molecule contains 10 hydrogen atoms. State the actual number of hydrogen atoms responsible for each peak.
