This sample of 1-bromopropane was prepared by the reaction of NaBr and H₂SO₄ in the presence of 1-propanol followed by distillation. The experiment was conducted by Jessica Chen in the undergraduate laboratory course (Chem 222La) during the fall of 2000. The triplet at δ 1.01 is the methyl group and the low field triplet δ 3.37 (t, 2H) is adjacent to the heteroatom. These five hydrogens are equally coupled (J = ~ 7 Hz) to the methylene group at δ 1.87 to produce the sextuplet.

The ¹³C spectrum displays the three carbon atoms at 36.06, 26.47, and 13.17 ppm. The signals are at the expected region of the spectrum. For a comparison of the ¹³C NMR spectra of n-propyl bromide and isopropyl bromide, click here. Return to Menu.
