Splitting of a signal in a proton NMR spectrum tells us the number of chemically non-equivalenthydrogens in the immediate vicinity of the hydrogen giving the signal. Predict the number of linesexhibited by hydrogens at the labeled positions in a first-order NMR spectrum. (Make theapproximation that all coupling constants are equal.)1)aCHbThe number of lines exhibited by hydrogen(s) a isThe number of lines exhibited by hydrogen(s) b isThe number of lines exhibited by hydrogen(s) c is2)BrabCThe number of lines exhibited by hydrogen(s) a isThe number of lines exhibited by hydrogen(s) b isThe number of lines exhibited by hydrogen(s) c is2
