Sketch an approximate mass spectrum of ethane (C2H6).
can you interpret the mass spectrum and assign the mass fragments ( write the strcture ) the compund is 2-chloro benzoic acid MASS SPECTRUM 40 80 120 160 200 m/z
In a mass spectrum for ethyl cinnamate, identify the fragments responsible for the possible peaks and draw a mechanism to show how they would form.
In this mass spectrum, which peak most likely represents the molecular ion? In this mass spectrum, which peak most likely represents the molecular ion?
(a) Draw the five major fragments of 3-chlorodecane that give rise to peaks in the 8 Mass Spectrum and provide their m/e values, showing the ratio of the peak values where applicable.
