Splitting of a signal in a proton NMR spectrum tells us the number of chemically non-equivalent hydrogens in the immediate vicinity of the hydrogen giving the signal. Predict the number of lines exhibited by hydrogens at the labeled positions in a first-order NMR spectrum. (Make the approximation that all coupling constants are equal.) 1) H₂N C The number of lines exhibited by hydrogen(s) a is 3 The number of lines exhibited by hydrogen(s) b is 6 The number of lines exhibited by hydrogen(s) c is 3 2) с The number of lines exhibited by hydrogen(s) a is 3 The number of lines exhibited by hydrogen(s) b is 6 The number of lines exhibited by hydrogen(s) c is 3
