A compound has the molecular formula, C6H15NO2. Its 1H NMR spectrum consists of two triplets at 2.8 ppm and at 3.5 ppm (integration for each triplet = 4H) and one singlet at 3.4 ppm (integration for the signal = 6H). The exchangeable proton appears as a broad signal at 2 ppm. The most likely structure for this compound is:

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
