Identify the C3H5Br isomers on the basis of the following information:

(a) Isomer A has the 1H NMR spectrum shown in Figure 13.42.

F I G U R E 13.42

The 200-MHz 1H NMR spectrum of isomer A (Problem 13.32a).

(b) Isomer B has three peaks in its 13C NMR spectrum: δ 32.6 (CH2); 118.8 (CH2); and 134.2 (CH).

(c) Isomer C has two peaks in its 13C NMR spectrum: δ 12.0 (CH2) and 16.8 (CH). The peak at lower field is only half as intense as the one at higher field.
