Which of the compounds will give the following 13C NMR and DEPT data? Broadband decoupled 13C (d ppm): 21.3, 127.2, 138.2 DEPT-135 (d ppm): 21.3 (positive peak), 127.2(positive peak) (A) (B) (C) (D)
Hi! can you please explain step by step how i would go about proposing a structure for this? I know that DEPT-90 shows CH groups & DEPT-135 shows CH & CH3 in the positive region and CH2 in the negative region. I also know that the normal graph shows the C's. However, i have answer to this question, but I have no idea how they came up with it. Can you please explain step by step your rationale how to...
