Enter your answer in the provided box. how many signals would you expect to find in the 1h nmr spectrum of 1−bromobutane? signals) in the 1h nmr spectrum of 1−bromobutane.

The ¹H-NMR of 1-Bromobutane is shown below,

There are Four signals found in the proton NMR spectrum of 1-Bromobutane.

Triplet Signal at ≈ 3.40 ppm (Down Field = Deshielded) is for methylene group directly attached to Bromine atom.

Multiplet Signal at ≈ 1.8 ppm is for methylene which is present between two methylene groups. The shielding effect is increasing as moving away from Bromine atom.

Multiplet Signal at ≈ 1.49 ppm is for methylene which is present between terminal methyl and methylene groups. The shielding effect is increasing as moving away from Bromine atom.

Triplet Signal at ≈ 0.9 ppm (Up Field = Most Shielded) is for terminal methyl group attached to methylene group.

Result:
           Four Signals are found in the ¹H-NMR of 1-Bromobutane.

Fine out your self ponk

No because it not possibly
