I'm working on characterizing a molecule based on CNMR spectra.
What does each peak represent and how to draw the chemical
structure based on this (with each C labeled)? 
Homework Answers
Dear Student,
I understand your CNMR problem but, only on the basic of CNMR i am find the exact structure, need some information below
a) Explain the reaction scheme or probable structure
b) have you done H NMR, if yes please provide H NMR graph
c) Need to IR spectra
Please raise your question again with maximum characterization so you get prefect answer
