A compound containing only C, H, and Cl was examined in a mass spectrometer. The highest mass peak seen corresponds to an ion mass of 52 u. The most abundant mass peak seen corresponds to an ion mass of 50 u and is about three times as intense as the peak at 52 u. Deduce a reasonable molecular formula for the compound and explain the positions and intensities of the mass peaks mentioned. (Hint: Chlorine is the only element that has isotopes in comparable abundances: Cl: 75.5 percent; Cl: 24.5 percent. For H, use H; for C, use C.)
