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...
