Below are shown three

C_(4)H_(8)Cl_(2)

isomers on the left and three sets of

^(1)H

NMR data that one would expect on application of the simple

N+1

rule on the right. Match the structures to the proper spectral data. (Hint: You may find it helpful to sketch the spectra on a piece of scratch paper.)\ (a)\ (i)
