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) bis 2 The number of lines exhibited by hydrogen(s) is c 2) The number of lines exhibited by hydrogen(s) a ls 2 The number of lines exhibited by hydrogen(s) bis 7 The number of lines exhibited by hydrogen(s) cls 2 How many kinds of chemically non-equivalent hydrogens are there in each of the following compounds? CI a CH-CH-OH --CH, The number of chemically non-equivalent hydrogens is CHH OH Ibuprofin, active enantiomer (antiinflamatory) b The number of chemically non-equivalent hydrogens is
