.26d Part 1 ✓ Your answer is correct. X Expected number of signals (enter a numerical value): 9 Mk

please don't provide hand writtin solution .......

Identify the spectra. All pertinent peaks must be assigned on spectrum (5-6 peaks). Label the peaks on spectrum.  I have provided the correct structure in the lower left hand corner, I just need help with labeling the peaks on the spectrum to match the structure.
