  • Rakesh is not quite right.

    It’s propyl propionate = CH3-CH2-CH2-O-C(=O)-CH2-CH3

    You can tell because the low field signal (ie the one at higher ppm) is a triplet. This means it must have two neighbouring protons, not three. Signals at ~3-4 ppm are often protons on carbons which are oxygen bound.

  • CH3-CH2-CH2-CO-O-CH2-CH3 or ethyl propanoate .
