Hello. I am having trouble figuring out this problem. May yoy explain how you got the answer for each? Thank you for your time and help. :)

PRACTICE PROBLEM 9.14 Compounds A, B, and C are isomers with the formula CsH44Br. Their broadband proton-decoupled 13C NMR spectra are given in Fig. 9.21. Information from the DEPT 13C NMR spectra is given near each peak. Give structures for A, B, and C. CHa A, CH, Br CH2 CH2 CH TMS CDCI 220 200 180 160 140 80 60 40 20 0 120 100 8c (ppm) B, C5H1 Br .
