The five compounds below all have a molecular weight of 148
g/mol. Start by drawing in all implied hydrogens on the printed
structures and then add up the chemical formula and molecular
weight for each to make sure you have everything correct. The
spectral data (EI-MS, IR, 1H NMR, and 13C NMR) for each compound
are grouped together (1 compound per page). For 1H NMR, numerals
underneath the spectrum represent integral values. **Compound A has
