Question

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.) 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 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

Explanation / Answer

Answar-1

Proton a will give 3 lines as triplet (t)

Proton b will give 4 lines as dd

Proton c will give 3 lines as triplet

Answar-2

Proton a will give 2 lines as d

Proton b will give 6 lines as dt

Proton c will give 2 lines as d
