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) The number of lines exhibited by hydrogen(s) a is The number of lines exhibited by hydrogen(s) b is The number of lines exhibited by hydrogen(s) c is| 2) a CN ÓCH, The number of lines exhibited by hydrogen(s) a is The number of lines exhibited by hydrogen(s) b is The number of lines exhibited by hydrogen(s) c is
