Determine the structure based on the molecular formula and its
1H NMR spectrum (and IR spectrum, if provided). Show the
work by providing a table summarizing the data from each spectrum
and explain in detail the reasoning. You must analyze each
absorption in the NMR and four absorptions in the IR (if
applicable).
The table for NMR should include: chemical shift (δ
value), the splitting, the number of neighbors, the integration,
and the assignment of the specific protons responsible for the...
