How many distinct resonances would appear in the (proton-decoupled) ¹³C NMR spectrum in the region between 100-130 ppm for the following compound?

Question

Quizplus · Accepted Answer

There are four distinct carbon environments in the compound based on the chemical shift values given: S1U (103 ppm), P1 (109 ppm), P11 (120 ppm), and C (128 ppm). Each environment will contribute a separate peak in the NMR spectrum, giving a total of four distinct resonances.
