Boron trifluoride is used as a catalyst in the synthesis of organic compounds. when this compound is analyzed by mass spectrometry (see tools of the laboratory, p. 55), several different 1 + ions form, including ions representing the whole molecule as well as molecular fragments formed by the loss of one, two, and three f atoms. given that boron has two naturally occurring isotopes, 108 and 113. and fluorine has one. 19f. calculate the masses of all possible 1 + ions.
