The molar mass of allyl chloride is 76.53 g/mole. However, the mass spectrum of allyl chloride shows M" at m/e 76 and relative intensity of 40%, an M+2)* at m/e 78 and relative intensity 14%. Select the correct explanation. a. The M* and (M-2)* peaks as well as the molar mass given are consistent with the relative natural abundance of chloriine isotopes. b. Carbon-14 in the sample gives rise to the smaller (M+2)* peak. Mass spectrometry can only show integer masses. C. Allyl chloride molecular ion with Me=78 loses H2 after ionization to give an ion with m/e = 76. d.
