How many lines would be seen in the ¹³C NMR spectrum of the product from the following reaction?

Question

Quizplus · Accepted Answer

The NMR spectrum of the product would have 4 lines. This is because there are two inequivalent proton environments in the product, one with three protons (S1U1P113S1S1) and one with one proton (S1P0C). Each proton environment will give rise to a multiplet of lines, with the number of lines dictated by the number of neighboring protons. The three protons in S1U1P113S1S1 will each see two neighboring protons, so each will give a triplet (3 lines), and the one proton in S1P0C will see one neighboring proton and give a doublet (2 lines). Therefore, the total number of lines in the spectrum will be 3+3+3+2 = 11, which simplifies to 4 lines after accounting for any overlap.
