For the reaction below, focus only on 2-methyl-2-butanol
(starting material) and 2-chloro-2-methylbutane (desired product).
We will not analyze HCl or H2O by IR.
From the two IR spectra below, identify which spectrum belongs
to which molecule. Then label the IR spectrum with the molecule’s
characteristic IR peaks. Highlight or place a box around the most
characteristic peak in the starting material’s IR. You do not need
to label the fingerprint region.

1. In the H NMR, draw the structure of the molecule directly on
the spectrum and identify each unique proton. Indicate which proton
is responsible for each peak.
2. In the IR spectrum, indicate which functional group is
responsible for each important peak. Attempt to identify at least
five important peaks. In you discussion, indicate which peaks are
most helpful in determining whether or not you converted the
starting material to the desired product.
