ELECTRON IMPACT MASS SPECTROMETRY PRODUCED THE SPECTRA BELOW. MANY PEAKS ARE LABELLED TO AID INTERPRETATION: M/Z (RELATIVE ABUNDANCE). LOOK AT THE HINTS AND FOLLOW THE WEB REFERENCE LINK FOR HELP. YOU WILL NEED A PERIODIC TABLE, A TABLE OF COMMON ISOTOPES (WHICH YOU CAN FIND IN THE WEB REFERENCE), A CALCULATOR, AND SCRATCH PAPER TO WORK THIS QUIZ.
