Distinguish between the \(^{\text{1}}{\text{H}}\,{\text{NMR}}\) spectra of 1-bromopropane and 2-bromopropane (splitting patterns are not required).

2-bromopropane will show two separate absorptions/peaks;

in the ratio 6:1;

1-bromopropane will show three separate absorptions/peaks;

in the ratio 3:2:2;

In (a) most candidates correctly determined the difference in the number of peaks in the \(^{\text{1}}{\text{H}}\,{\text{NMR}}\) spectra of 1- bromopropane and 2 – bromopropane but neglected to mention or misinterpreted the differences in area under the peaks.
