Structure elucidation is made even simpler with the help of the 1H NMR and the 13C DEPT spectra. Give the structure corresponding to the data below. [The identity of the carbons was determined using the DEPT experiment.]
C6H11BrO2 IR: 1735 cm ⁻¹
1H NMR δ 4.09 (t, 2H), 3.27 (t, 2H), 2.85 (t, 2H), 1.81 – 1.70 (m, 2H), 0.96 (t, 3H).
13C NMR δ 171.56 (C), 66.13 (CH2), 37.21 (CH2), 26.14 (CH2), 22.29 (CH2), 10.36 (CH3).
