Question
the top line reads: The mass Spectra of three isomeric amines, sec-butylamine, isobutylamine, and tert-butylamine are given. Decide which Spectra belong to which amines and write equations justifying your conclusion.
a nc uass opecua are given in Figure 21.12. Decide which spectr be justifying your conclusions. ui unee isomeric amines, sec-butylamine, isobutylamine, and tert-butylamine, longs to which amine, and write equations 100 80 60 40 - 20 20 40 60 80 100 120 140 160 100 80 60 40 20 20 40 60 80 100 120 140 160 100 80 60 40 20 20 40 60 B0 100 120 140160Explanation / Answer
The first spectrum shows a peak at nearly 60 mass/charge ratio (highest among the given three). This indicates the presence of a high mass compound or more mass accumulated at a junction. Hence it is related to tert-butylamine as it contains a tertiary carbon junction.
The second spectrum has mass to charge ratio at nearly 45 (second highest). In sec-butylamine, one carbon is attached to 2 carbon, 1 NH2 and 1 H (secondary carbon). This means the mass at this carbon will be high(But not as High as Tertiary carbon).Hence this spectra is related to sec-butylamine.
The third spectrum has the peak at 30 (least of all). Hence it is related to isobutylamine.
