In the 1H NMR of isoamyl alcohol, which protons are responsible for the triplet at 3.6 ppm?
proton at 3.6 represent the -OH proton
this -OH proton is exchangable proton
that is why instead of shorp singlet this will come as a triplet
(CH3)2CHCH2CH2OH is iso amyl alcohol,Carbinolic protons -*CH2OH is responsible for resonance at delta 3.6 ppm in 1H-nmr dur to high electronegative OH group attached with -CH2. And as a triplet due to neighbor CH2 attached with CH2OH.

Label 1H NMR peaks for Isoamyl acetate? Here is the 1H NMR spectrum I have for isoamyl acetate. The question says to clearly assign all peaks. Any help would be greatly appreciated. Thanks!
