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 make the structure using the information given? i.e. also how we know how many CH's & CH3's we have. Thank you so much!!

could someone show me step by step for this
such as how to go about/get dy/dx etc.
i know the final answer is 4 pi ^2 ab , but I can't seem to get
there as no one shows the steps
when I attempt it I end up with 2pi instead of the correct
4pi
