Answer :
Explanation:
The attached file shows the HNMR of methyl propanoate. The hydrogen atoms on the CH3 attached to the CH2 have a chemical shift of 1.14 being in the same chemical environment. The hydrogen atoms on the CH2 have the same chemical shift of 2.29 being in the same chemical environment and close to the COO group. The hydrogen atoms on the CH3 attached to the COO group have the highest chemical shift of 3.67, being very close to the electronegative element (i.e Oxygen).
