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.)
