How many signals will be observable in the DEPT ¹³C NMR spectrum of naphthalene (shown below)? A)0 B)1 C)2 D)3 E)10

Question

Quizplus · Accepted Answer

The DEPT spectrum distinguishes between CH, CH2, and CH3 groups based on their signal intensities. In naphthalene, there are two types of CH groups (those attached to the outer ring and those attached to the inner ring), which will give rise to two signals in the DEPT spectrum. Since there are no CH2 or CH3 groups present in naphthalene, options A, B, and D can be ruled out. Option E (10 signals) is too high for a simple aromatic compound like naphthalene, hence the correct choice is C (2 signals).
