For each of the above compounds, do the following:
1. List the wave numbers of all the IR bands in the 1350-4000 cm$^{-1}$ region.
For each one, state what bond or group it represents.
2. Label equivalent sets of protons with lower-case letters. Then, for each $^1$H NMR
signal, give the $\delta$ value, the type of splitting (singlet, doublet etc.), and the number of
protons it represents.
letter
$\delta$ value
splitting
# of protons
3. Redraw the compound and label equivalent sets of carbons with lower-case letters.
Then for each $^{13}$C NMR signal, give the $\delta$ value and # of carbons it represents.
letter
$\delta$ value
# of carbons
13
