How many ¹³C signals would you expect from anisole?

Question

Quizplus · Accepted Answer

Anisole has two different types of carbon atoms, one is connected to two hydrogen atoms and the other is connected to one hydrogen atom and one methoxy group (-OCH3). The two carbon atoms connected to two hydrogen atoms will produce a singlet peak and the carbon atom connected to the methoxy group will produce a triplet peak due to spin-spin coupling with the three hydrogen atoms on the methoxy group. Therefore, the expected number of ¹³C signals from anisole is two, representing the two different types of carbon atoms.
