    Solution:

     I) Please, allot-to specious structures to the ions at m/z 157, 142, 100, 85, and 58 detected in the EI spectrum of N-methyl-N-isopropyl-valerimide. Indicate distinctly the dishonorable peak and the molecular ion peak. (30 points) 100% CH CH3 )CH-N -CH2-CH2-CH2-CH 3 CH3 100 115 157 2 85 80 100 120 140 160 m/z 20 40 60

    Please, allot-to specious structures to the ions at m/z 157, 142, 100, 85, and 58 detected in the EI spectrum of N-methyl-N-isopropyl-valerimide. Indicate distinctly the dishonorable peak and the molecular ion peak.
