Explanation / Answer

Identification of compound

IR shows

2800-3000 cm-1 for sp3 -C-H stretch

1H NMR shows, all peaks in aliphatic region

13C NMR shows three peaks in aliphatic region at 27 ppm, 38 ppm and 43 ppm

Mass shows two peaks at 121 and 123 ppm in 1 : 1 ratio (M-1) peaks, so presence of Br isotopes.

Possible structure of compound,

CH3-CH2-CH2-Br
