How many signals would you expect to find in the 1h nmr spectrum of 1 butanol?

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

There are Five signals found in the proton NMR spectrum of 1-Butanol.

A Broad Singlet signal at ≈ 4.7 ppm (Down Field = More Deshielded) is for proton directly attached to Oxygen atom.

Triplet Signal at ≈ 3.65 ppm (Down Field = Deshielded) is for methylene group directly attached to Oxygen atom.

Multiplet Signal at ≈ 1.6 ppm is for methylene which is present between two methylene groups. The shielding effect is increasing as moving away from Oxygen atom.

Multiplet Signal at ≈ 1.4 ppm is for methylene which is present between terminal methyl and methylene groups. The shielding effect is increasing as moving away from Oxygen atom.

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

Result:
           Five Signals are found in the ¹H-NMR of 1-Butanol.

Cis the answer ur welcome if i get it wrong u don't have to me
