Following are the ¹H and ¹³C spectra for two isomeric bromoalkanes (A and B) with formula C₄H₉Br. Integral curves are drawn on the spectra, along with relative integral values provided just above the scale and under each set of peaks. These numbers indicate the relative number of protons assigned to each pattern. Remember that these integral values are approximate. You will need to round the values off to the nearest whole number. Also, in some cases, the lowest whole-number ratios are given. In such cases, the values provided may need to be multiplied by two or three in order to obtain the actual number of protons in each pattern.
